President Trump escalated his war of words with Anthony Scaramucci on Monday, calling the Mooch "highly unstable" in an early morning tweet storm. Scaramucci joined Cheddar to unpack the string of insults.

The Twitter tirades are “malicious, bullying of individual citizens, which is a form of fascism,” Scaramucci said. He also slammed Trump for attacking him while the “world is crumbling around him,” citing a slew of policy failures, such as the failure to sign a trade deal with China.

Scaramucci is the founder of Skybridge Capital and served as the White House communications director for 11 days in 2017. His brief tenure ended after he gave an expletive-filled interview disparaging other Trump administration officials.

When asked about his decision to accept the job in Trump's administration, Scaramucci said, “I made a mistake … but I think it is important to call out what’s going on for what it exactly is. And I intend to continue to do that."

Scaramucci also mentioned that he is working on an effort to find a Republican primary challenger to Trump in 2020.

"Let's try to re-engineer, re-establish where the Republican Party needs to go," although he said he is still trying to find potential challengers to the president.

Trump also drew the ire of the Mooch on Monday for attacking his wife — “a complete and total civilian,” Scaramucci said.
