椭圆形办公室
The C&amp;O desk is one of only six desks ever used in the Oval Office by a sitting President of the United States. The C&amp;O Desk was used there only by George H. W. Bush, one of two Oval Office desks (along with the Johnson desk) to be used by only one president. Prior to its use in the Oval Office by Bush, the desk had been used elsewhere in the White House. It is the shortest-served Oval Office desk to date, having been used for only one four-year term.
