WASHINGTON -- Anthony Scaramucci, who was the White House communications director for 11 days back in 2017, threw the latest punch in his internet feud with President Donald Trump, predicting that he will drop out of the 2020 presidential race by March in a no-holds-barred interview with Vanity Fair published Friday.

“It’s gonna become very clear that it’s impossible for him to win,” Scaramucci said. “And is this the kind of guy that’s gonna want to be that humiliated and lose as a sitting president? He’s got the self-worth in terms of his self-esteem of a small pigeon. It’s a very small pigeon.”

The comments come following a week of tweeting back-and-forth and derogatory statements to the press between the two men.

In a tweet Monday, the president said Scaramucci "had nothing to do with my Election victory." Trump also suggested Scaramucci's recent criticism was motivated by the fact that his former aide "is only upset that I didn’t want him back in the Administration (where he desperately wanted to be)." The president added that Scaramucci "just wanted to be on TV!"

Scaramucci, who has been nicknamed “the Mooch,” had kicked off the war of words when he said on CNN he could no longer support the president after seeing his reactions to the mass shootings in Texas and Ohio.

“The red line was the racism—full-blown racism. He can say that he’s not a racist, and I agree with him, okay?” Scaramucci told Vanity Fair’s William Cohan.

He continued: “He’s actually worse than a racist. He is so narcissistic, he doesn’t see people as people. He sees them as objects in his field of vision.”

Scaramucci said he hopes a Republican will run against Trump, who he called "this jack*ss," in the primary and win. “And so listen, there’s gotta be somebody in the Republican Party that’s worried about 2024 and the identity of the Republican Party.”

But in the battle to take Trump down, Scaramucci said he bases his attacks on Trump's leadership abilities, not on personal qualities.

“I’m not calling him Small Hands or saying he’s got a small penis. I’m not doing any of that. I’m attacking him by asserting presidential leadership; this is where the bar is, this is where you are,” Scaramucci said. “You’re bullying. You’re angry. You’re detached.”

“You know, this is like ‘Game of Thrones.’ We need an Arya Stark, okay? We gotta take this guy out because this is like the Night King,” Scaramucci said, referencing the icy villain who poses a danger to humanity in the HBO series.

“We had the Wicked Witch of the West, but he is the Wicked Witch of the West Wing. We gotta get some water thrown on him. He’ll start melting,” Scaramucci said.
