Move over, George Clooney. Democratic Presidential candidate Bernie Sanders is among the guests set for Stephen Colbert's second week behind the Late Show desk. The Sept. 18 appearance marks Sanders' second late-night visit as he ramps up his run for the White House. He was most recently a guest on Late Night With Seth Meyers in June. Colbert's lineup shows his desire for a wide variety of guests reaching well outside the normal Hollywood channels. His first week of guests includes celebrities like Clooney as well as Republican President candidate Jeb Bush and the CEOs of Tesla and Uber, respectively.
