'Major loser': Trump lashes out at former pal and White House staffer

Former Donald Trump adviser and short-lived communications director Anthony Scaramucci triggered his ex-boss enough that he took time out of his busy pre-inauguration schedule to lash out on TruthSocial.

Trump shared an appearance of Scaramucci on CNBC last week, during which Squawk Box host Joe Kernen asked if he was "embarrassed or at least humbled about how wrong you were."

The ex-Trump adviser said that he “immediately put out a congratulatory tweet. They won, we lost." It was a stark contrast to those who refused to accept the 2020 election results.

“What would you like me to do? Do you want me to get on bended knee before you?” Scaramucci asked the host. “We have a violent disagreement about lots of things related to Trump’s personality. You like Trump — I was close to Trump, I got to see the ugliness of what he is. And by the way, Joe, it’s not just me.”

Kernen lashed out, saying that "The Mooch" has benefited considerably from his short time with Trump. The response led Scaramucci to tell the host to "calm down."

"Why don’t you calm down a second, Joe,” Scaramucci told him. “We know each other a long time. Are you saying that you and I can’t disagree on somebody’s personality? Is that what you’re saying?”

The exchange prompted Trump World to cheer on Kernen, claiming Scaramucci got owned.

Trump quickly followed, calling his former hire "a major loser who was fired from the Administration after only 11 days for his insane 'brother from another mother' interview with Chris Cuomo, then with CNN!"
