I guess Donald Trump and Stephen Bannon won’t be exchanging Christmas cards any longer.

Bannon, the former chief strategist in the Trump White House, has decided to turn on his former boss-friend by writing in a new book that Don Trump Jr.’s meeting with a Russian lawyer during the 2016 presidential campaign was “unpatriotic” and “treasonous.” Oh, and Trump’s son-in-law Jared Kushner and former campaign chief Paul Manafort were there, too.

The president’s response may go down in political annals as a classic. He fired off a statement that declared that Bannon has “lost his mind,” that he had little to do with the victory that Trump scored in the 2016 election and that Bannon was the primary reason Republican U.S. Senate candidate Roy Moore lost an Alabama election he was supposed to win.

As one CNN analyst said, Trump in effect turned a flamethrower on his former top White House aide.

According to CNN: “Steve Bannon has nothing to do with me or my Presidency. When he was fired, he not only lost his job, he lost his mind. Steve was a staffer who worked for me after I had already won the nomination by defeating 17 candidates, often described as the most talented field ever assembled in the Republican party,” Trump said in the statement. 

Well … I guess this means Trump no longer has any relationship with Bannon. To think that Bannon declared after he was let go from his White House job that he would be the president’s best friend and most loyal political ally. Bannon pledged to carry Trump’s message forward.

What does Bannon’s published statement mean to the investigation that special counsel Robert Mueller is conducting? Hmm. I suppose it might mean that it piques the curiosity of Mueller’s legal team enough to question Bannon extensively on what he means by “unpatriotic” and “treasonous.”

Oh, the hits just keep coming.
