On Thursday, President Donald Trump went after MSNBC show “Morning Joe” and its hosts, former Congressman Joe Scarborough and commentator Mika Brzezinski.

Trump wrote on Twitter that Scarborough is "Psycho Joe," while Brzezinski is "low-I.Q., Crazy Mika."

He also took a shot at Brzezinski over a supposed face-lift.

Following the tweets, many Republicans and even supporters of President Trump have come out and urged him to stay on message and quit with the personal attacks.

Tucker Carlson said it's a "real tragedy" that the tweets distract from Trump's agenda, Meghan McCain said they are "beneath the dignity of the White House," and Charles Krauthammer said they "degrade the political discourse."

Several Republicans lawmakers also shared their reactions to Trump's tweets:

A brand-new Fox News poll found that many Americans agree with those assessments of Trump's Twitter habits.

On "Happening Now," Howard Kurtz said Trump has had a great legislative week, but he has an "uncanny ability to step on his own story."

"Even his own allies acknowledge that," Kurtz said.

Heather Childers pointed out that CBS Evening News covered the tweets for two minutes and 34 seconds. Meantime, they only covered the travel ban for 20 seconds, while they completely ignored the House passing Kate's Law and a sanctuary city bill.

Watch more from Kurtz above, and share your reaction in the comments.
