Sanders, a famously private senator, became a regular on the talk show and late-night circuit as a 2016 Democratic presidential candidate. He appeared on Colbert’s show last November, just days after Trump’s election victory.

Sanders has two events scheduled in New Hampshire over the Labor Day weekend, intensifying speculation that he may run for the White House again in 2020.
