On Tuesday President Obama will pay another visit to NBC’s “The Tonight Show” host Jay Leno. It will be his fourth appearance on the program. Leno was the comedian at the 2010 White House Correspondents’ Dinner. Many felt he bombed, telling jokes that he recycled from his show. In March of 2009, Obama was criticized for appearing on the show at a time when the economy was in a shambles. During that visit, White House poolers were not permitted in the NBC studio during the taping of the show. We hope they have a nice food court nearby.
