Stephen Colbert had to sit down to talk about the renewed feud between President Donald Trump and the U.S. senator he refers to as "Pocahontas" Monday night. "Well, after years of mocking Elizabeth Warren, clearly the president must have had a lot to say about these test results," the Late Show host said of the Democratic senator's decision to put out confirmation that she does, in fact, have some Native American ancestry. "You care!" Colbert told the president.
