Senator Bernie Sanders and actress Lupita Nyong'O are the latest to take the hot seat at The Late Show to talk shop with host Stephen Colbert. Sanders - the surprising frontrunner in the race for the Democratic presidential nomination - offered up his very brief opinions on a host of issues. He also explained his refusal to take the word "socialist" as an insult. Nyong'O talked her upcoming New York stage debut in playwright Danai Gurira's Eclipsed, which opens next month. She and Colbert also take their best shots at doing a silly walk.
