As Colbert himself said so memorably in 2005 on the Daily Show, describing the true purpose of the White House Correspondents' Dinner:

"[P]articularly in recent years, the correspondents' dinner has served as a night of genial detente for the press and the White House; a chance for each side to say to the other, "You know what? Deep down, we're both entrenched oligarchies with a stake in the survival of the status quo. Enjoy your scrod, old buddy. Enjoy your scrod."
