The fight between Donald Trump and his former communications director, Anthony Scaramucci, isn’t remotely slowing down.

Trump on Monday lashed out at Scaramucci, who served as White House director of communications for less than two weeks, after Scaramucci’s latest morning show interview in which he blasted the president and again said Republicans should replace him on the 2020 ticket.

Trump described Scaramucci’s White House tenure as “11 days of gross incompetence,” also alleging he “abused staff,” bringing up his divorce, calling him a “mental wreck,” and lobbing at him what is, in the president’s world, the worst insult imaginable: that he was “bad on TV.”

Anthony Scaramucci is a highly unstable “nut job” who was with other candidates in the primary who got shellacked, & then unfortunately wheedled his way into my campaign. I barely knew him until his 11 days of gross incompetence-made a fool of himself, bad on TV. Abused staff,…

….got fired. Wrote a very nice book about me just recently. Now the book is a lie? Said his wife was driving him crazy, “something big” was happening with her. Getting divorced. He was a mental wreck. We didn’t want him around. Now Fake News puts him on like he was my buddy!

This is just the latest instance of Trump going after a former administration official he hired as grossly incompetent, having previously declared former Secretary of State Rex Tillerson “totally ill prepared and ill equipped” for the job.

Trump’s tweets came after Scaramucci’s latest morning show interview on CNN, during which he said Trump is “off his rocker” and is destroying “the social fabric of the United States,” while claiming that “everyone inside” the White House knows this. Scaramucci continues to predict Trump will drop out of the 2020 race by next March.

Scaramucci has noticed his former boss’ latest tweets, and he has a statement from his wife about how they don’t approve of it:

My wife @DeidreScaramuc2 response: “I don’t really like being tweeted at by @potus on a Monday morning but at least I had my coffee!” More to follow . . . @moochandthemrs https://t.co/dLRAyiWpDU
