Sen. Bernie Sanders (I-Vt.) was the "mystery guest" on Thursday's episode of "The Late Show," packing a lot into his 4-minute surprise appearance.
Sanders and host Stephen Colbert chatted about superdelegates, with the presidential hopeful arguing that they "should listen to the will of the people" and vote for him against former Secretary of State Hillary Clinton. Some superdelgates in New York have said they will vote for Clinton no matter who wins the state's primary election on April 19, according to the New York Daily News.
Sanders also "saved" an employee hiding behind Colbert's desk during his appearance, and showed off his skills with a t-shirt cannon.
