Jon Stewart mocks Trump at USO event with David Letterman

Jon Stewart tells troops Donald Trump will keep them busy while hosting a USO event attended by David Letterman

Jon Stewart took a few jabs at presumptive Republican nominee Donald Trump while hosting a USO event celebrating the organization’s 75th anniversary. The former Daily Show host compared the billionaire’s controversial campaign rhetoric to some of the “crazy” things Joe Biden has said in the past.

“He’ll say whatever he kind of thinks of, whatever comes to his mind, sort of impulsive,” the comedian said when introducing the vice president. “Sometimes, you might think to yourself, ‘That sounds crazy,’ or ‘Man, that is crazy. And who would have thought that now, that gets you the Republican nomination.”

The remarks were met with laughs and groans from the audience, which was filled with members of the military. Stewart quickly added, “Don’t worry, Trump’s going to keep you busy when he’s the commander-in-chief. You’re going to have to repaint all the planes with ‘Trump’ in big, gold letters.”

Biden, who has been outspokenly critical of Trump, took exception to the comparison, turning the tables on Stewart – who sported a baseball cap and gray beard – once he took the stage. “I was going to say something nice about Jon, but to hell with him,” he joked.

Stewart’s absence has been felt during this year’s unpredictable election season after he stepped down as host of The Daily Show last summer. He has since signed a four-year deal with HBO to produce such projects as short-form videos, which could premiere ahead of the 2016 presidential election.

Fellow retired late-night host David Letterman also appeared at the event, which was held at Joint Base Andrews in Maryland, and was attended by President Obama, First Lady Michelle Obama and Biden’s wife, Jill. Stewart was much more complimentary during his introduction of Letterman, comparing him to the pope and the Johnny Carson for his generation of comedians. During his speech, the former Late Show host said that he was just “happy to be out of the house,” joked about being mistaken for poet Walt Whitman based on the appearance of his burly white beard, and later mocked Stewart for his casual attire, saying, “I’m guessing trouble with the luggage.” Watch his entire speech here:

Letterman went on to introduce a birthday cake to celebrate the organization’s milestone anniversary, and led the group in an off-key rendition of “Happy Birthday,” which led Obama to quip that the event was clearly meant for comedians and not singers. The United Service Organizations (USO) offers services and provides live entertainment to U.S servicemen and their families. The show also featured performances by such comics as Judd Apatow, Jeff Ross and The Daily Show‘s Kristin Schaal and Hasan Minhaj.

“You are in store tonight for what will be … the best show in the United States tonight,” Letterman concluded. “Except maybe Hamilton.”
