Donald Trump Jr. criticized former White House Chief Strategist Steve Bannon Wednesday in a series of tweets following President Trump’s scathing criticism of his former advisor. Trump Jr. said “minus the foul language The Mooch pretty much nailed it” in relation to off-color remarks former White House communications director Anthony Scaramucci made about Bannon. He also said that Breitbart’s founder would be “ashamed” of Bannon and mocked Bannon’s backing of Alabama Senate candidate Roy Moore.

“I’m not Steve Bannon, I’m not trying to suck my own c---. I’m not trying to build my own brand off the f---ing strength of the president. I’m here to serve the country,” Scaramucci said in July in an expletive-laden rant to The New Yorker's Ryan Lizza.

Wow, Just looked at the comments section on Breitbart. Wow. When Bannon has lost Breitbart, he’s left with . . . umm, nothing. — Donald Trump Jr. (@DonaldJTrumpJr) January 3, 2018

According to excerpts from author Michael Wolff’s new book, Bannon called Trump Jr.’s meeting with a Russian lawyer in Trump tower on the campaign trail “treasonous” adding that Trump Jr. “should have called the FBI immediately.”

Following the release of these excerpts, President Trump released a scathing statement about Bannon Wednesday, writing that when Bannon was fired “he not only lost his job, he lost his mind.”
