Stopping by the Tonight Show in 2009, President Barack Obama became the first sitting president to appear on a late-night talk show as he discussed the economy with Jay Leno. He had already appeared in 2006 and 2007, and the First Lady dropped in on the NBC studios in Burbank, Calif., in 2008.
After his first presidential appearance, Obama took flak from critics who said he was disparaging the office by sitting down with Leno. Then-spokesman Robert Gibbs responded by saying that the show simply gave Obama a “unique audience” to which to deliver his message.
