Author Kristin Tate believes President Trump made a mistake Wednesday by getting into a war of words with his former chief strategist and Breitbart News executive Steve Bannon. 

Trump fired back at Bannon, who in a new book harshly criticizes the Trump team for a "treasonous" meeting with a Russian lawyer in 2016.

Firing back in a statement, Trump said Bannon "lost his mind" after being fired from the White House last August and downplayed Bannon's role on the campaign and in the administration. 

"Steve had very little to do with our historic victory, which was delivered by the forgotten men and women of this country. Yet Steve had everything to do with the loss of a Senate seat in Alabama held for more than thirty years by Republicans. Steve doesn’t represent my base—he’s only in it for himself," said Trump.

Tate, who used to work at Breitbart, said Trump "looks really bad right now" and is risking alienating part of his base by "personally attacking" Bannon. 

"All Trump has right now is his base. It's a very strong base and if he alienates them, he has nothing," she pointed out. 

Tate said Trump needs to use his "fantastic, unorthodox style" to focus on what his supporters care about, like repealing ObamaCare, building the wall and lower taxes.

She said it's "nonsense" for Trump to claim Bannon didn't help him win the presidency. 

"When Bannon came into the campaign, it was a disaster. [Paul] Manafort had no idea how to control a candidate who was so unconventional. Bannon knew to let Trump be Trump, he knew how to connect Trump to his base," Tate argued. 

Democrat and Fox News contributor Jessica Tarlov said Trump has now "disowned" several former members of his campaign, including Paul Manafort and George Papadapoulos.
