Donald Trump has often taken aim at various late night personalities, but he appears to harbor a special animosity towards Jimmy Kimmel — a subject that David Letterman addressed on Tuesday night’s episode of Jimmy Kimmel Live! “Are people aware that you are the figurehead of the resistance?” Letterman inquires in the video, proceeding to share his endorsement for Kimmel. “On the topic of leaders, allow me to state one thing here. I’m going to flatter you, because I believe that if I sort of associate myself with you, I’ll be celebrated in hindsight. Now, this has nothing to do with party or political beliefs. If the head of the free world is a lunatic, then that individual should be prepared for and reflect on every ounce of mockery he encounters.” In the meantime, Amber Ruffin also stood up for Seth Meyers concerning Trump’s remarks about the Late Night host.
