'He Lost His Mind': Trump Hits Back After Bannon Calls Russia Meeting 'Treasonous'

Scaramucci: Author's Claim That Trump Didn't Want to Win Election Is 'Nonsense'

Several Republican congressional candidates backed by Steve Bannon are distancing themselves from the former White House chief strategist after President Trump said Bannon had "lost his mind."

Trump issued a blistering statement about Bannon on Wednesday after the release of excerpts from a forthcoming book that quoted Bannon's strong criticism of the president, his family and his team.

“Steve Bannon has nothing to do with me or my presidency,” Trump wrote. “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 seventeen candidates, often described as the most talented field ever assembled in the Republican Party.”

Bannon-backed Senate hopefuls Kelli Ward and Patrick Morrisey have since denounced Bannon's remarks and reinforced their support of Trump.

On "Your World," Michael Grimm, a Republican House candidate from New York who was supported by Bannon, said he worked with Bannon for one purpose: to help advance Trump's agenda.

"I will not work with anyone that doesn't want to help our president and get that agenda where it needs to be, which is across the finish line," Grimm told host Neil Cavuto.

Grimm added that the investigation into possible collusion between the Trump campaign and Russia is a political witch hunt, and Bannon just fed into the left's narrative with his remarks about what he called a “treasonous” and “unpatriotic” meeting between members of the Trump team and a Russian lawyer during the 2016 campaign.

"Anything that feeds into that is hurtful and harmful to the presidency. And I simply can't support that at all," Grimm said.
