Two former Daily Show correspondents reunited Wednesday on The Late Show as Stephen Colbert was joined by Last Week Tonight host John Oliver. Before Jon Stewart left The Daily Show in July, he expressed regret that he was departing as Donald Trump's political popularity was ascending. (Colbert too overindulged on Trump during his premiere Late Show episode.) Oliver, however, has a different attitude toward the Republican frontrunner. "I couldn't give less of a shit. It's physically impossible," he said of the mogul.
