When a new first family sets foot inside of the White House on Inauguration Day they are walking into their new home for the next, usually, four to eight years. That means their furniture in the living, their pictures on the wall, their clothes in the closets. The only hitch is that the outgoing first family is supposed to feel at home up until the moment they leave the White House — also on inauguration day. What does that mean? Approximately six hours while the cat’s away to totally transform a 132-room mansion. The Washington Post’s Bonnie Berkowitz investigated this question a few years ago — she shares what she uncovered.
