Former House Speaker Newt Gingrich believes Steve Bannon's days are numbered after his explosive public back-and-forth with President Trump.

Gingrich was at the Capitol on Thursday for a meeting with Senate Majority Leader Mitch McConnell, R-Ky. As he left, he was asked if Bannon could survive his battle with Trump.

“No,” Gingrich mouthed while nodding his head as he exited the Capitol. “No,” he reiterated.

That reply came a day after Trump said Bannon “lost his mind” after he left the White House. Trump was responding to excerpts of a book in which Bannon said Donald Trump Jr.’s decision to accept a meeting with Russians was “treasonous.”

A McConnell spokesman didn’t say what he discussed with Gingrich in his meeting.
