MSNBC's Joe Scarbrough slammed Republican lawmakers on Monday for selling out to, asking in an interview with CBS "Late Show" host: "What job is worth selling your political soul for?"

“That’s what I don’t understand, what job is worth selling your political soul for?” asked Scarborough, a former GOP congressman from Florida who left Republican Party during Trump's presidency. “You can look at the people who are running in Republican primaries, and you can predict what they’re going to do. It’s very disappointing."

Scarborough announced on Colbert's show more than two years ago that he was leaving the Republican Party due to Trump and Republican lawmakers' loyalty to the president. He formally switched to being a political independent in October 2017.

Scarborough also once said Trump first "pledged his fealty and loyalty" to Russian President Vladimir Putin Vladimir Vladimirovich PutinFBI chief says Russia is trying to interfere in election to undermine Biden Traces of nerve agent found in water bottle in Navalny's hotel room, colleagues say Russia: US trying to foment revolution in Belarus MORE, while accusing Republicans of "going on national television repeating Putin talking points" in December.

“Donald Trump is either an agent of Russia or he’s a useful idiot. Or he’s somewhere in between, we don’t know what it is,” he alleged late last year.

Trump has not appeared on "Morning Joe" or MSNBC since May 2016, going back to his days as a candidate.
