'Morning Joe' Hosts Nix Vacation to Address Trump Tweets: 'Fascinating, Frightening and Really Sad'

'I'm fine," Brzezinski said Friday. "My family brought me up really tough."

Mika Brzezinski and Joe Scarborough were supposed to be on vacation Friday, but the Morning Joe co-hosts instead went on the air to address President Trump’s string of tweets about them.

“You know what, I think it’s been fascinating and frightening and really sad for our country,” Brzezinski said.

The duo, who are reportedly engaged, were the target of tweets from the president, who claimed that Brzezinski was "bleeding badly from a face-lift” when the pair went to Mar-a-Lago around New Year’s Eve.

He also dubbed the hosts "Psycho Joe" and "Low IQ Crazy Mika," in the Thursday Twitter rant. 

“I’m fine, my family brought me up really tough,” she said Friday. “But I am very concerned as to what this once again reveals about the president of the United States.”

“We’re okay," Scarborough chimed in. "The country’s not."

He added. “We have friends inside the White House that have told us over the past month they’re getting more concerned about his emotional state."

The hosts also claimed that the president has used a possible National Enquirer hit piece to blackmail them.

"We got a call that, 'Hey, the National Enquirer is going to run a negative story against you guys' and they said, 'If you call the president up, and you apologize for your coverage, then he will pick up the phone and basically spike this story,'" Scarborough said. “I have texts from your top aides and phone records."

“Watched low rated @Morning_Joe for first time in long time. FAKE NEWS. He called me to stop a National Enquirer article. I said no! Bad show,” he wrote.

“We have no knowledge of any discussions between the White House and Joe and Mika about our story, and absolutely no involvement in those discussions,” Enquirer editor Dylan Howard told CNN in a statement.
