Some viewers were surprised with the host Jon Stewart's tough questioning of Obama during his first appearance on the show as a sitting president. Stewart pressed Obama on a number of topics Democrats had recently been criticizing the president on, like healthcare and repealing the military's 'don't ask, don't tell' policy.  But the White House deemed the appearance a "success."

"Our viewpoint is that when the president gets to talk about what he's done and sit through what people may or may not have heard, it's a positive benefit," then-White House Press Secretary Robert Gibbs said in 2010. 

"So I would think of it as a success."

Obama has appeared on the show four other times, twice in 2008, once in 2007, and once in 2005.
