In what’s become something of an embarrassing national tradition, Donald Trump this week took to Twitter and blasted MSNBC Morning Joe co-host Mika Brzezinski. In a pair of tweets, Trump called Brzezinski “low I.Q. Crazy Mika” and then later referenced a New Year’s Eve meeting where he said “she was bleeding badly from a face-lift.” Predictably, Trump’s tweets were widely criticized, with even prominent Republicans coming out and stating that Trump’s behavior was decidedly un-presidential.

“I’m fine,” Brzezinski said of the tweets. “My family brought me up really tough. This is absolutely nothing for me personally. But I am very concerned about what this once again reveals about the president of the United States. It’s strange.”

Chiming in on the matter, Stephen Colbert couldn’t help but throwing a few targeted jabs in Trump’s direction on last night’s episode of Late Show with Stephen Colbert.

“I want to say something right now that I did not think was possible anymore,” Colbert said at the top of the episode. “I am shocked by something Donald Trump said. I thought by now, after five months of this, that my soul had calcified into a crouton. Not true.

“First of all,” Colbert continued, “someone bleeding badly at your door and you say ‘no’? It sounds like your health care plan. I think turning them away from your hotel during the middle of winter is literally the story of Christmas. Only there wasn’t a wise man in sight. This is shocking and viscous, and so on-brand.”
