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. And now nearly a decade ago, then-fresh television sensation Stephen Colbert was invited to talk at the White House Correspondents’ Dinner as the featured entertainer . . . and give Bush, Jr. his due.
The then-senior editor for The New Republic Noam Scheiber subsequently wrote the following in 2006: “I’m a big Stephen Colbert fan, a huge Bush detractor, and I think the White House press corps has been out to lunch for much of the last five years”.
