Stephen Colbert and Jimmy Kimmel find creative ways to hear John Bolton's testimony

Senate Majority Leader Mitch McConnell (R-Ky.) is confident he has the votes to block any witnesses from testifying in President Trump's impeachment trial, "but here's the thing: 75 percent of Americans support calling witnesses in this trial," Stephen Colbert said on Thursday's Late Show. The would-be star witness is former National Security Adviser John Bolton, whose forthcoming book reportedly details a first-hand account of Trump saying he was withholding $400 million in Ukraine military aid to force investigations of Democratic rivals — "a shocking revelation of something we've all known for months," Colbert said.

Still, if he did testify, nobody knows what Bolton would even say, Colbert noted, so he had him (or at least Dana Carvey in a fake mustache) on "via live satellite" to ask. Carvey's Bolton had a lot to say, very energetically.
