On CNN New Day:
"We do begin with breaking news in the Mueller investigation," John Berman said.
"A source tells CNN that deputy attorney general Rod Rosenstein plans to leave the Justice Department, once William Barr, the president's nominee for attorney general, is confirmed. That will likely happen sometime in February. Barr's confirmation hearing begins next Tuesday. And I have to say, the stakes just went up in a big way. We should note our sources say Rosenstein is not being forced out. He has overseen the special counsel's Russian investigation for more than a year. And with him gone, it means an oversight of the probe will be led by people who have expressed open and public hostility to at least parts of it."
