The White House Correspondents’ Association dinner isn’t quite what it used to be. When it was started in 1921, White House correspondents’ and a few of their guests were the only people in attendance. Today, Hollywood runs the show using D.C. as it’s backdrop. Our colleague Roxanne Roberts writes that it is “a Washington-themed party with little to do with Washington.” Roberts introduces you to the celebrities who are responsible for the dinner’s evolution in the video above.
