Original subtitles

[narrator] It is home to the most powerful person in the world.

It is a center of global military power.

And it is one of the most heavily protected fortresses ever built.

But behind the classic columns and lush, green lawns are secrets.

Secrets so outrageous...

[Joseph W. Hagin] Some systems were installed post-9/11,

but I don't want to talk about it.

[narrator] ...so controversial...

They were right with the president, and they hadn't even been invited.

[narrator] ...so dangerous...

In the event that there might be a threat,

there are ways of moving the president in the White House.

[narrator] ...that they must be kept hidden from the public.

[Ronald Kessler] The White House is a Mecca for all these nuts

who want to go after the president,

so they will show up at the White House, and, uh, try to get in.

[narrator] There are those who believe in the existence of a book.

A book that contains the most highly-guarded secrets

of the United States of America.

A book whose very existence

is known to only a select few.

But if such a book exists, what would it contain?

Secret histories? Secret plans?

Secret lies?

Does there really exist

America's Book of Secrets?

It is the most public of private residences.

And the most private of public buildings.

Because while the White House serves as home and office

for each American president, it is also home to the First Family.

[Steven Ford] The best way to describe it is,

it's like living in a museum.

It's kind of hard to feel comfortable, to make it your own.

The hardest adjustment is the press

and the comings and the goings.

For me to get from the house to my dad's office,

you'd have to walk by the press room.

It was people always knowing where you are

and what you're doing, and notifying people.

[Steven] I used to walk by the White House,

just like you or I would,

and look through those bars, those gates, and wonder what the heck they do in there.

And all of a sudden, ten months later, I find myself standing there,

because my dad's become President of the United States.

It didn't make any sense.

The Nixons left so quickly, so unexpectedly.

I mean, the resignation was unexpected at that time.

And they didn't have time to pack up all their belongings and their clothes.

So that night, we had to go back to our little house in Alexandria, Virginia,

and we lived in that house for the first six, seven days of Dad's presidency.

[narrator] Little preparation can be given

for the radical changes the First Family will face

while living at the White House,

especially when it comes to the loss of privacy.

[Steven] You might walk by one of the tours.

As you're coming in, they might be going by

and going to the East Room or the Blue Room

or something like that, and you would see them, and I--

a lot of times, I'd stop, shake hands, say hello.

You know, it's your home, but you're also welcoming the public.

I think people would be surprised

by the private White House is a very artificial place.

Presidents don't get a lot of privacy.

Presidents are sort of living a very abnormal existence.

So you wonder how they cope with this.

Some do better than others.

One of the classic stories about that, you know,

that realness of, this is what happens, uh...

My parents had a golden retriever, Liberty,

and one night, Liberty woke Dad up and had to go to the bathroom.

So Dad put his bathrobe on over his pajamas,

came down the family elevator to the first floor of the White House

and went out, I think it was the diplomatic entrance.

And here it is, like, two o'clock in the morning.

He takes the dog out to do its business,

like any husband has to do in their own home.

He gets ready to go back in, and the door's locked,

and the Secret Service don't know he's out there.

And here's the President of the United States,

at 2:00 in the morning, standing there in his pajamas,

trying to get his dog back in the house, and the door's locked.

[Susan] I think of us as, who've lived there,

as a fraternity or a sorority or a club.

We don't know everybody.

You don't get to know them very well,

but you have secrets that only you can tell each other.

[narrator] To ensure the safety of the First Family,

every aspect of their daily needs is monitored,

including the food they eat and the gifts they receive.

The food that goes into the White House

is screened at a remote site, before it ever gets to the White House itself.

So a lot of precautions are taken

to ensure that whatever meals or whatever food

that's going to be provided at the White House

is thoroughly screened.

[Kessler] If food comes as a gift, unless it's from someone

who's a very close friend or family member,

the Secret Service will just throw it away.

And I think, you know, even friends and family learn

that they shouldn't bring food into the White House.

[narrator] Protecting those who live and work at the White House

extends not only to the food they eat,

but also to the very air they breathe.

[Kessler] In the White House itself, when people enter,

they're automatically put through not only, of course, metal detection,

but also detection of radiological devices.

The air in the White House is filtered.

The air in the White House also is increased in pressure

so that if there is some biological element introduced,

it'll be expelled.

[Natasha Neeley] The West Wing has radiation detectors.

And I know this because when I was giving a West Wing tour,

Secret Service, I believe, got a silent alarm,

or something came in over their earpieces

and they locked down the area that we were in.

And they said that someone had brought in some form of radiation,

and they needed to figure out what it was

before anyone was allowed to move forward or leave the area.

It turned out that someone was going through radiation therapy,

but I found that really interesting to learn

that they have those type of security things

that they don't just advertise, even to all staff.

[narrator] Of course, the White House

is not only the Chief Executive's home and office.

It is also a command center for nearly 1,700 employees

who come to work there every day.

But before anyone works for the president or his family,

they must be cleared

through a background check known as Yankee White.

[Walsh] Everybody who gets cleared into the White House permanently,

as a regular thing, has to go through a secret security clearance process,

to look into your background and so on.

[Neeley] When I first was asked to be an intern,

we were told to fill out a form called an SF-86,

which, basically, is where they ask you

every single little detail about your life.

Um, more than you ever could remember.

And you're going through old pictures, old notes.

Being, like, "Oh, my gosh, what was that address ten years ago?"

And, "Oh, what date did I go on that trip?"

And then the FBI goes around and investigates

to make sure everything on that SF-86 is accurate and true.

They interview your friends, your family, your neighbors,

your old bosses to make sure that they know every single thing about you.

[narrator] But once employed, can the White House staff

and personnel go anywhere within the building,

or are there secrets so highly prized and highly guarded

that only a handful of the most trusted employees can have access to them?

There are pins that people use, they have on their lapels,

in addition to the badges that people might see on TV images.

The pins are the most prized,

because you can get the close access to family badge,

where you can get pretty much all the access.

That's what-- the First Lady would wear those,

the children, and so on, and some very senior staff members.

[narrator] But if White House employees are so thoroughly checked and monitored,

how do visitors and members of the public get in?

How hard is it to visit the White House?

And what kind of security is required

to protect the world's most powerful person?

[narrator] While the White House serves as the private home

of one of the world's most highly guarded families,

it is also the only residence of a head of state that is open to the public.

And although security at the Executive Mansion has tightened over the years,

interest in visiting 1600 Pennsylvania Avenue

has existed for centuries.

[Walsh] If there was a passage

in America's Book of Secrets on the White House,

it probably would deal with the security there,

because it used to be that it was thought of as the People's House.

Presidents, years ago, would entertain everyday people

who could just walk to the White House,

get in and talk to the President.

[Claire Whitcomb] Souvenir hunting has been a problem

at the White House over the two centuries of its existence.

After Lincoln's second inaugural,

there were people cutting the crimson curtains.

They must have come armed with pocket knives and things like that.

Pieces of carpet were cut. It was just pillaged.

[narrator] Believe it or not, even famous celebrities

have shown up at the White House uninvited.

On December 21, 1970, Elvis Presley appeared at the gates,

asking to see President Nixon.

And although the rock and roll dignitary known as The King was welcomed in,

his visit was very much kept under wraps.

[Kessler] It was all done secretly

because Nixon didn't want to let the public know that he was seeing Elvis.

Like everybody else, Nixon was enamored with Elvis and his songs,

and at the same time, he thought it would be embarrassing

if the public knew that he had an interest in meeting Elvis Presley.

[narrator] But for the thousands who visit the White House each year,

access to certain areas of the home

and the president are strictly off limits.

And when access is breached,

it becomes a matter of national security.

On November 24, 2009,

400 guests attended a White House state dinner

honoring the Prime Minister of India.

Among the attendees were Tareq and Michaele Salahi.

According to the White House, the couple had arrived uninvited.

But if so, how did they manage to get past

one of the tightest security systems in the world?

How could a suburban couple get past several security checkpoints,

dozens of plainclothes uniformed security agents,

and the Secret Service?

At the first gate, we present our real names, we show our real IDs.

And the Secret Service agent at the first entrance is going through the guest list,

doesn't immediately see our name on the guest list,

but tells us to proceed to the second checkpoint. And we do.

[Basham] A very confusing situation existed there at the first checkpoint,

there at 15th and E Street, and one individual decided

that these individuals looked like they belonged.

I don't know how else to explain it.

[narrator] After gaining access onto the White House grounds,

the Salahis passed through a second security checkpoint

stationed near the main building.

[Salahi] We are in a line. We meet with Katie Couric.

She's in line with us. We start chatting with her.

And we are getting checked in now.

So now there's this another Secret Service checkpoint here.

This person was not in a uniformed Secret Service outfit.

This person was in coat and tie. And at this point, there's a checklist.

And they're checking everybody off.

And we present our I.D.'s, present our real names,

and we get checked off at the second checkpoint.

We're now proceeding into the White House, into the reception area

where there are magnetometers and X-ray machines.

And we get screened from, you know,

purses to going through the metal detector.

We go through that, get processed there and checked in.

We're now in a line, a line going into the,

uh, if you will, the red carpet

of the White House where you're announced.

[ANNOUNCER] Mr. and Mrs. Salahi.

[Salahi] It's an incredible feeling

and it's just an honor being in the White House.

Especially being announced by the White House,

being welcomed by the White House.

And at this point, we are-- we are-- this is better than our wedding.

We found ourselves in the receiving line to meet the President.

And we met with the President of the United States, President Obama.

Then the First Lady.

And then the Prime Minister. And then his wife.

[Walsh] They had their pictures taken with the president, which is remarkable,

because they were right with the president and the First Lady,

and they hadn't even been invited.

So that was the worst breakdown,

certainly, at a social event, that I've ever seen.

And that caused a huge fuss,

and people were fired over that, or left because of that.

There were undeniable planning and execution failures

of the entire Secret Service apparatus.

[narrator] While the Salahis maintain

that they had come to the White House event as invited guests,

many believe the secret to their successful entrance

was merely looking the part.

The Salahis were actually able to talk their way in.

It's not that they were particularly known, that's what made it so bizarre,

but they were all dressed up and they looked like they belonged there.

[Kessler] But when the Salahis crashed the state dinner

at the White House, they were not on the guest list.

They had not been cleared by the Secret Service, as a result,

and the Secret Service uniformed officers simply ignored the fact

that they were not on the guest list.

Usually, the security at the White House is very intense,

and at the social events, it's very intense.

They have staff members from the social secretary's office,

with lists of people who are entitled to come in, who are invited.

There's a number of those folks at the gates always checking people off.

Then they have another checkoff. And there's still another list.

But in this particular case, the system broke down.

[narrator] But while the Salahis undoubtedly became

the White House's two most infamous unwanted guests,

there were only a handful who knew about the other,

even more mysterious visitor who attended the same event that night.

The same night that the Salahis crashed the state dinner,

there was a third intruder, Carlos Allen.

And the way that he was uncovered

was that Secret Service surveillance cameras

spotted him going to the dinner, and nobody knew who he was.

They knew that he was not on the guest list.

They finally figured out who he was.

He had intruded with the Indian delegation,

got into the White House,

and the Secret Service again ignored the fact

that he was not on the guest list.

[Basham] It just demonstrates

that all of the work of all of the people

and all of the systems and all of the processes,

one individual, if they don't do their job,

can literally destroy all of that work. It wasn't a pleasant time.

I feel confident, based on what I've heard,

based on what I've seen, based on what I've been briefed on,

that they did not provide a risk to the president.

[narrator] But while uninvited guests

may be more of an embarrassment than a security threat,

how is the White House prepared

to deal with more serious and secret situations?

And what rooms and tunnels exist within its walls

that can help protect the president and the nation during a deadly attack?

[narrator] It is one of the most critical

intelligence gathering centers in the world.

Located in the West Wing, just below the Oval Office,

the Situation Room

serves as an advanced communications headquarters

where America's commander in chief

can monitor and control U.S. military forces around the world.

One of the subjects brought up with every President-elect,

as soon as he becomes elected,

as part of his briefings, is the Situation Room

and how it works and the information that comes in.

Mr. Obama, for instance, on his first day in office, went down to the Sit Room

and participated in a conversation with some of his military people.

There's a huge misperception in the general public

about what goes on down there.

They think it's just a meeting room, but it really is more than a room.

It's an intelligence center.

[narrator] Measuring approximately 5,000 square feet,

the Situation Room's technological capabilities are for now top secret.

Today, the President could not do his job without the White House Situation Room.

First and foremost, the Situation Room is the President's alert center.

Their most important responsibility is to make sure

the President knows what's going on around the world.

Secondly, it's a meeting room, a place where he can go,

either in crisis or meet with his advisors in a secure, safe place.

Thirdly, it's his communications center, and whether it's dedicated communications

between the President and the Prime Minister in Great Britain,

or whether it's a connection to the CIA's communications systems

or DOD's, it's all the same.

[narrator] But while it is officially called the Situation Room,

White House insiders know it by another, more secret name.

One of Nixon's aides, who later became the national security advisor

to President Clinton, Tony Lake, Alexander Haig said,

"Come on, you want to go with me to the Situation Room?

Henry Kissinger is going to take the CIA to the woodshed."

Lake thought the room was the Woodshed,

so it ended up getting that name.

[John F. Kennedy] It shall be the policy of this nation

to regard any nuclear missile,

launched from Cuba against any nation

in the Western Hemisphere, as an attack.

[narrator] It was the disastrous Bay of Pigs Invasion

in 1961 that prompted President John F. Kennedy

to create the Situation Room as a way to improve real-time communications,

current intelligence and crisis support.

The previous Presidents had been hostage to the State Department

or Defense or Intelligence for information.

And he realized during the Cuban Missile Crisis

that he couldn't really run the government

unless he had a more rapid arrival of information at the White House.

So he arranged to build a facility on the ground floor of the White House,

and he called it the International Situation Room.

And it was shortened to the Situation Room.

[narrator] National Security Advisor McGeorge Bundy

equipped the center with state-of-the-art technology,

including a hotline to the Russian Kremlin.

But, contrary to popular belief,

the famous hotline was not, in fact, a telephone.

[Hagin] The hotline to the Kremlin was a Teletype device.

It allowed for more security of the information

that was flowing across it.

Someone felt that by not being a voice connection,

eliminated confusion from translation

and it was easier to communicate very precisely,

which would be needed in an emergency.

That degree of precision was increased

by having a written word versus a spoken word.

[narrator] But during the Cold War,

few knew that the White House installed another secret phone system.

The State Department established what was called

the warm link as an alternative to the hot link,

in order to foster more routine communications.

But it was an alternative

because people wanted to keep the hotline for crises only

and not diminish its circumstance.

In fact, Carter went against that grain and used it for routine communication.

And Brzezinski warned him not to do it

because it would perhaps undercut the importance of it during crises.

[narrator] Like the rest of the White House,

the Situation Room has been renovated and rebuilt

and has grown in size, scope and strategic importance

as the threats to the nation have changed.

[sirens blaring]

[Hagin] Following 9/11 and during a period of war,

the Situation Room really proved inadequate in terms of its capabilities.

We made the decision that the facility needed to be modernized.

We needed more conference rooms to have classified conversations in.

And then the facility was really taken down

to the brick and the dirt floor.

It was totally gutted top to bottom and in the process of doing that,

we exposed a lot of very old wiring.

And it's a miracle that the West Wing's not burned to the ground.

[narrator] Today, the Situation Room, or Sit Room,

is composed of approximately 30 personnel

organized around five watch teams

that monitor both domestic and international events.

The Situation Room, of course, is on duty 24 hours a day,

seven days a week, with a staff of people on duty there.

And these telegrams come in from State or from Defense

or CIA constantly in the Situation Room.

If it's anything that is significant for the President,

they'll wake him up right away.

There are no levers that the President reaches over and pulls

or twists knobs or pushes buttons to launch missiles

and all that sort of thing.

What happens is he meets with the people that he trusts in that room,

and then they go off to their places,

and that's where they push the buttons and pull the levers.

[narrator] Several times each day,

the teams distill the latest real-time information

into reports that are prepared for the president.

[Bohn] The CIA, the Director of National Intelligence

in the CIA sends down a once daily president's daily brief,

which has the most sensitive information available

and gives it to the President.

But right next to it in the folder is the Situation Room daily summary,

which goes out three times a day. And that covers everything else.

And so the president keeps track of things on a daily basis

through the help of the Situation Room.

This is the watch floor of the White House Situation Room.

And the watch floor's commodity is situational awareness.

We're a fusion center, meaning that we fuse approximately

2,000 pieces of information every day.

One of the cool features of this particular room

in the White House Situation Room is the opportunity to provide privacy

for the President if he's making a head-of-state phone call

from the Situation Room itself.

And what we'll do is we'll be able to fog the windows

to give him that level of privacy.

Now the President can engage in face-to-face,

top secret teleconference conversations with other leaders of the world.

He's got that equipment, for instance, with the Chancellor of Germany,

with the Prime Minister of the United Kingdom,

and with military people like General Petraeus.

[Hagin] There's the famous picture in the Situation Room

of President Obama and Secretary Clinton

and the staff during the mission that went after Osama bin Laden.

The capability certainly exists within the Situation Room

to watch live broadcasts.

I don't believe any other leader in the world

has the communications and technology capabilities

that are available to the President of the United States.

And that's the way it has to be.

[narrator] But as much as the Situation Room can help

the president function during a national crisis,

just how safe is the White House from a physical attack?

[narrator] In 2010, a major classified construction project

broke ground on the north lawn of the White House.

While officials claim the work was to upgrade utilities

for the East and West Wings,

the project's top secret price tag led many to speculate

it was a much more serious undertaking.

But could the project really have been intended to serve a more secret purpose?

[Kessler] The new construction at the White House grounds

is simply more facilities in the event of an attack to guard the President

and to allow the White House to function with many aides,

even though an attack may be occurring.

[Hagin] A lot of the information

regarding the president's safety and security,

and that of the White House, by their nature, have to remain secret.

You can't give your adversaries a hand

in understanding how to defeat your systems and your procedures.

It is secret and it'll remain so.

[narrator] Over the past 200 years,

the function of the White House has grown beyond

just being the president's personal residence.

It has become the nation's center of executive power,

a strategic location that has required the home

to become more like a fortress.

[President Roosevelt] December 7, 1941,

a date which will live in infamy.

[William Seale] Pearl Harbor was such a shock.

Engineers then, they began to look after the President's safety.

Many people wanted him to move and to go somewhere else

to a secret place, but he wouldn't do it.

And he said, "The President belongs here."

Of course, President Roosevelt was in a wheelchair.

And so that worried them even more about moving him around.

So several things came up.

One was that they closed off all the skylights.

They covered them all with paint.

He did let them put wet sand in a bucket and a gas mask in every bedroom.

[narrator] But what never changed

was the color of the structure, even in times of war.

They asked President Roosevelt if they could paint the house camouflage.

Camo. [laughs]

And he said, "No, you cannot."

[narrator] But perhaps one of the biggest of the White House's many secrets

is the fact that the current building is actually less than 70 years old,

having been extensively remodelled in the late 1940s

by President Harry Truman.

[Seale] Truman's daughter Margaret's piano leg

fell through two boards, and they said, "Out."

So he moved to Blair House.

And a survey was done of the house, and the Corps got to Truman.

One of the men told me,

who was an engineer who surveyed the house at that time,

that you could walk between the plaster ceiling

and the wooden structure of the East Room.

I mean, you couldn't stand up, but it was four feet if dropped.

[narrator] After securing the funds from Congress,

Truman authorized the 147-year-old residence

to be gutted from the inside

and meticulously rebuilt from the original blueprints.

But was the construction done purely for the safety of the First Family

or might there have been another, more secret reason?

Was the renovation an opportunity

to clear the house of any Cold War spying devices?

Or was it an occasion to harden the executive offices

against any potential atomic threats?

Between 1948 and 1952,

engineers replaced all the wood-frame substructure

with concrete and state-of-the-art steel beams.

[Seale] They tore off the attic and roof

and created a new roof that was a bigger pitch,

but not so much that it would be a hat from the street.

And they added some bedrooms and some storage rooms and things,

all in steel.

They built a steel structure just inside the original walls

and new foundations were given to the original wall,

so they don't support anything but themselves.

And each room is a steel cage.

And the whole house was rebuilt in steel

and then the plaster put on steel lath.

And the idea was that it would be a house for the ages.

[narrator] Today, the exterior sandstone walls

are all that remain of the original White House.

But could Truman's extensive renovation project

have really been a cover for changes to the building

that were meant to be hidden from the public?

Changes similar to the those undertaken in 2010?

Research on the effects of a Hiroshima-sized explosion

set off at a midpoint along Pennsylvania Avenue

suggest that the White House,

with its reinforced concrete, low-lying silhouette

and large surrounding buildings,

would sustain less damage than the Capitol Building.

Equally critical to ensure the president's protection

are the invisible defenses built into the White House itself.

While the exact specifications remain classified,

it is believed the entire building has been modified

to be practically bulletproof.

Not long ago,

this is what you needed to protect against armor-piercing.

As you can see, it's about four inches thick.

It's a combination of glass and polycarbonates.

And though it's very clear, it's still very heavy, very thick.

It's an intense piece of product.

Since then, the glass has gotten much thinner.

And actually, there are even space-age polymers

available this thin and light.

It also has amazing stopping power.

A very lightweight material.

Once you've protected your glass,

you want to start considering your walls, ceilings and floors.

Now, if you can imagine,

this is the kind of thing that is typically done

in buildings to achieve a Level Seven.

Level Seven is armor-piercing.

So, if we were to be doing a high-level government facility,

say something like the White House, it would be reasonable to assume

that you'd have something like this throughout the walls, ceilings and floors

of the rooms that you really wanted to protect against projectiles coming in.

[narrator] Is it possible that the president

is heartening the White House even further,

perhaps expecting a direct attack?

While the White House is fortified against acts of war,

just how vulnerable is the President and his family

to an attempted assassination?

[narrator] In the age of terrorism

and political assassination...

[gunshots]

...just how safe is the White House?

And are there secret measures in place

to keep the President and his family secure?

The White House is sort of a Mecca for all these nuts in the world

who want to just go after authority.

The president is the top enchilada.

And so they will show up at the White House

and try to get in.

[Basham] The Service takes those threats,

regardless of whether it's against the president,

the vice president, members of the family,

the White House itself,

very seriously,

and investigates to make sure that they get a full understanding

of exactly what that threat is and how to mitigate it.

[narrator] The first lines of defense

against White House intruders are the visible deterrents,

such as the iron fence lining the perimeter

and the guards patrolling the White House grounds.

But there are also security measures hidden from the public eye.

The White House grounds are protected

by a complete array of sensors that detect heat, motion.

If anything is detected, the Secret Service comes running.

The uniformed officers of the Secret Service, in particular,

are in charge of guarding the White House grounds and the White House itself.

And they have dogs that will attack an intruder.

If necessary, they will shoot the intruder to kill him.

[Perino] The Secret Service is one of the most professional organizations.

They put their lives on the line every single day protecting the president.

[gunshots]

[narrator] Over the years, a number of armed

or otherwise dangerous intruders

have attacked the White House.

In 1974, Robert Preston, a young Army private,

hovered above the south lawn in a stolen helicopter.

White House guards responded with a barrage of gunfire,

forcing Preston to land.

Slightly injured and clad in fatigues, the hijacker was apprehended

and admitted for psychiatric observation.

I, George Walker Bush, do solemnly swear...

I, George Walker Bush, do solemnly swear...

-[siren wailing] -[gunshots]

[REPORTER] ...gunshots, the sound of gunshots

on the south side of the White House.

[narrator] In February, 2001,

two weeks after George W. Bush's inauguration,

Robert W. Pickett, a former IRS employee

with a history of mental illness and suicide attempts,

waved a gun at tourists and police outside the White House,

firing several shots.

A Secret Service agent shot him in the knee after a ten-minute standoff.

November 11, 2011. Oscar Ortega-Hernandez,

a 21-year-old man from Idaho,

fired a semi-automatic assault rifle from a passing car.

The bullets struck near the residential quarters.

Recently, you had a situation

where there was someone shooting at the White House.

Fortunately, they had the appropriate level of security there

that prevented any penetration of those rounds

from actually getting into the interior of the White House itself.

[narrator] But one of the most unusual attacks

on the White House came on September 11, 1994.

Just before midnight, Frank Corder,

a 38-year-old Army veteran suffering from depression,

stole a Cessna plane and flew it towards the White House.

Seven minutes out,

air traffic controllers stationed at the National Airport

picked up the Cessna on their radar screens.

But it was too late.

Corder crashed the plane directly on the south lawn,

missing the White House by just a few feet.

While reports indicate Corder committed suicide,

many speculated that he was, in fact, shot down.

Could there be, as some believe,

anti-aircraft missiles on top of the White House?

And people just assumed that the White House

had all of those defense mechanisms in place,

and when this Cessna flew into the White House,

people were asking, "How can that happen?"

But since then, I can assure you,

there have been defense mechanisms put in place

that would prevent that sort of situation from happening again.

If you go back, in the Washington Post, when we were in the Bush administration,

there was a picture on the front page

of some systems that were installed post-9/11.

So you can unearth your own secret,

that way, but I don't want to-- I don't want to talk about it.

[narrator] But with all the corridors, offices, tunnels,

and secret areas of the White House,

is there one area that is the safest and most secure of all?

A place where the president and his family

can go in the event of a national emergency?

Obviously, I'm not going to be able to say specifically,

but just let's say that there are ways of moving

the president and the First Family around

in the event that there might be a threat in the White House.

[narrator] Some speculate that the safest area

of the White House is the secret underground facility

located below the East Wing, known as the PEOC,

or President's Emergency Operations Center.

Originally constructed as a bomb shelter

by President Franklin Roosevelt during World War II,

the PEOC has been designed to withstand a nuclear attack.

It's in the East Wing basement. It's an old World War II bomb shelter

with a great, big, heavy door, full of bunks,

and canned foods, canned water, and all that.

Cheney, Condie Rice,

and a few other people rode out the storm on 9/11 in the PEOC.

[narrator] With the contingency plans seamlessly followed on 9/11,

the nation and its leaders can be confident

that the most public of private homes is today safe and secure.

For over 200 years, the White House has more than

met George Washington's original intention:

To house, serve, and protect

the President of the United States and his family.

But perhaps the greatest secret the White House holds

is that each passing president is a temporary resident

in what is actually a home that belongs to every American.

I look at our family and, God, what a blessing.

I mean, to live there at that very unique time.

This is America's home, it's not our home.

You want to cherish it, you want to enjoy it,

but you want to respect it.

It's not the First Family's home, it's America's home.
