But easily the most awkward moment in Colbert’s career, and also in many ways a defining one, was his appearance at the White House Correspondents’ Dinner in 2006. Mark Smith, an A.P. reporter who, as head of the correspondents’ association, was responsible for booking the talent, admitted later that he wasn’t all that familiar with the show, which was only three months old when he approached Colbert. Neither, to judge from video of the event, were many in the audience. Colbert got up and addressed the president, saying: “I stand by this man because he stands for things. Not only for things. He stands on things. Things like aircraft carriers and rubble and recently flooded city squares. And that sends a powerful message: that no matter what happens to America, she will always rebound — with the most powerfully staged photo-ops in the world.”
