It depends on what you mean by The White House. The Executive Office of the President currently has about 1,869 full-time equivalent employees. That includes everyone who works for the president who doesn't report to another executive department or agency. Secret Service agents, for example, work at the White House, but are employed by the Department of Homeland Security. The EOP also includes a lot of people who work for the White House, but not at The White House. In fact, most of them work in the Eisenhower Executive Office Building next door, or the New Executive Office Building, or one of the converted townhomes on Jackson Place across Pennsylvania Avenue.
