The appearance will be Clinton's first on a late-night show since announcing her bid for the Democratic presidential nomination and just the latest in her list of TV appearances as the 2016 presidential race draws near. Her interview with ABC News' David Muir airs Tuesday night and she's appearing on The Ellen DeGeneres Show on Thursday, Sept. 10.
Fallon certainly won't be hard-pressed for at least one good topic of conversation when Clinton visits. After all, he's interviewing Republican contender Donald Trump the week before on Friday, Sept. 11.
If anything, maybe Clinton will help write some Thank You notes for her opponents?
