Joe Scarborough and Mika Brzezinski on "Morning Joe." MSNBC President Donald Trump walked back some criticisms he laid against "Morning Joe" hosts Mika Brzezinski and Joe Scarborough in a Twitter outburst on Saturday morning, saying their bosses at NBC are to blame for the low ratings received by "Crazy Joe" and "dumb as a rock Mika."

"Crazy Joe Scarborough and dumb as a rock Mika are not bad people, but their low rated show is dominated by their NBC bosses. Too bad!" Trump tweeted.

The back-handed compliment follows a savage attack on Brzezinski earlier in the week. He tweeted that Brzezinski once visited his Florida estate, Mar-a-Lago, while she was "bleeding from a face-lift." Top Republican lawmakers denounced Trump's tweets in the days following.

Trump's feud with the media ramped up this week, following the dismissal of a top conservative host from MSNBC and the forced resignation of three CNN reporters.

MSNBC abruptly fired host Greta Van Susteren five and a half months into her new posting, which Van Susteren confirmed on Twitter on Thursday. The network reportedly saw viewership plummet during the conservative host's 6 o'clock hour.

On Saturday, Trump took aim at the network and Comcast, which owns NBCUniversal.

"Word is that @Greta Van Susteren was let go by her out of control bosses at @NBC & @Comcast because she refused to go along w/ 'Trump hate!'" Trump tweeted.

Also this week, three CNN reporters resigned under pressure after publishing a story that tied a Trump transition team member to a Russia-related investigation. Some hailed the move as a show of accountability. The White House jumped at the chance to bash the network.

"I am extremely pleased to see that @CNN has finally been exposed as #FakeNews and garbage journalism. It's about time!" Trump tweeted.

In a brief departure from his assault on the media, Trump lashed out at the more than two dozen states that have refused to cooperate in a voter fraud investigation.

"Numerous states are refusing to give information to the very distinguished VOTER FRAUD PANEL. What are they trying to hide?" Trump tweeted.

A presidential commission is seeking extensive "voter roll data" in an effort to gather evidence that supports Trump's claim — that three million to five million people illegally voted in the 2016 presidential election. Democratic state officials have been brazen in their objections.
