From the Second City, An Extended First Family

Quoted via Washington Post:

See slideshow of Obama family and friendsA bus filled with about 50 of President Obama's friends and in-laws arrived at the White House just after midnight, as Inauguration Day came to a close, for what they called a "housewarming party." The group had celebrated more than a dozen moves together over the years, usually with casual dinners in bungalows on the South Side of Chicago. This time, they wore rented tuxedos and gowns as a small army of presidential staffers ushered them past Secret Service agents and into the East Room.

Marian Robinson, Michelle Obama's mother and the family matriarch, came downstairs from her new bedroom, and the family reunited on an oak parquet floor underneath crystal chandeliers. Celebrities and political power brokers greeted them. Jazz legend Wynton Marsalis played trumpet while caterers handed out hors d'oeuvres and flutes of champagne.more
