Reliable Source: Celebrities who shook up the White House Correspondents' Dinner

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.
