.... I think that's where the bulk of the Pottery Barn redocrating went after they moved in.
Still not sure I like that burlap on the walls, but hey, if The Obama needs to be surrounded by burlap to help him get stuff done, then so be it.
Originally part of the offices of the president on the White House's second floor, this room was used by several presidents as an audience or waiting room. It was partitioned near the windows to allow Abraham Lincoln to pass from the Library (Yellow Oval Room) to his office in today's Lincoln Bedroom without encountering anyone.
The room has been a Cabinet meeting room since Andrew Johnson. When James Garfield was shot, it was turned into a kind of ice-house, where various crude air-conditioning machines were installed in an attempt to make the president more comfortable. William McKinley presided over the signing of the peace treaty with Spain in this room in 1898, which ended the Spanish-American War. The artist Theobald Chartran was inspired by that event to paint a depiction of it, which today hangs in the very room itself.
That treaty, and many others before and since, was signed on what is known as the "Treaty Table," a magnificent Victorian desk originally used as a Cabinet meeting table by Ulysses Grant and commonly used today by presidents as a desk.
Theodore Roosevelt and William Howard Taft both displayed personal memorabilia going back to their college days. During World War I, Woodrow and Edith Wilson returned to his desk here after dinner to decode classified dispatches transmitted earlier in the day.
Some presidents between McKinley and Kennedy used the Yellow Oval Room next door instead and made this room into a sitting room. Wilson lined the walls with low bookcases. Under Coolidge, floor-to-ceiling bookcases were built along the walls. The Hoovers tore them out and converted the room into the "Monroe Room" parlor, decorating it with Monroe-period furniture or replicas and later the "Rose Parlor." Eleanor Roosevelt replaced some of it with sturdier pieces from the furniture factory she helped found, and briefly held her press conferences for women reporters here. Dwight Eisenhower used this room (along with the Solarium) for his frequent bridge games.
During the Kennedy administration, the room was remade as the "Treaty Room" in memory of the Spanish peace protocol, with dark green walls and carpet in an early Victorian pattern and a Grant-era East Room chandelier. John Kennedy himself signed the Partial Nuclear Test Ban Treaty in this room on October 7, 1963. Mrs. Kennedy, and later, Mrs. Ford, used this room as a work space (Rosalynn Carter was the first to have her office in the East Wing).
