The WHCA's annual dinner, begun in 1920, has become a Washington, D.C. tradition and is usually attended by the President and Vice President. Fifteen presidents have attended at least one WHCA dinner, beginning with Calvin Coolidge in 1924. The dinner is traditionally held on the evening of the last Saturday in April at the Washington Hilton. The WHCD has been increasingly criticized as an example of the coziness between the White House press corps and the Administration. The dinner typically includes a skit, either live or videotaped, by the sitting President in which he mocks himself, for the amusement of the press corps.
