Former White House communications director Anthony Scaramucci shot back at President Trump over Twitter, following some blistering tweets from his former boss.

Scaramucci, who served in the role for only 11 days, said that Trump has recently been making comments that “divide the country” and offered a warning about the president.

“For the last 3 years I have fully supported this President. Recently he has said things that divide the country in a way that is unacceptable. So I didn’t pass the 100% litmus test. Eventually he turns on everyone and soon it will be you and then the entire country,” Scaramucci, 55, tweeted Sunday morning.

Scaramucci, nicknamed “The Mooch,” said Thursday that Trump’s trip to El Paso, Texas, following the recent mass shooting was a “catastrophe.” Trump responded Saturday that Scaramucci knows little about him or the administration.

“Anthony Scaramucci, who was quickly terminated (11 days) from a position that he was totally incapable of handling, now seems to do nothing but television as the all time expert on 'President Trump.' Like many other so-called television experts, he knows very little about me…

“…other than the fact that this Administration has probably done more than any other Administration in its first 2 1/2 years of existence. Anthony, who would do anything to come back in, should remember the only reason he is on TV, and it’s not for being the Mooch!”

Scaramucci was fired after an expletive-laden rant to a reporter at the New Yorker, which accused then-White House chief of staff Reince Priebus of leaking information.

“What I want to do is I want to f---ing kill all the leakers and I want to get the President's agenda on track so we can succeed for the American people,” Scaramucci said during the phone call, which was later published.
