Rod Rosenstein, the US deputy attorney general who oversaw the inquiry into alleged Russian meddling, is to step down by mid-March, US media say.
Rosenstein was reportedly planning to leave the Justice Department soon after William Barr's confirmation as attorney general. As CNN has reported, Attorney General Bill Barr has selected Jeffrey Rosen, the deputy transportation secretary, as his deputy.
CNN's report on Rosenstein's departure notes that a replacement for the Deputy AG "could be announced as early as this week".
According to McCabe, in a lengthy interview that aired Sunday on CBS's "60 Minutes", Rosenstein brought up the possibility of invoking the 25th Amendment of the US Constitution, which provides for the removal of a sitting president for incapacity.
The Justice Department has said McCabe's characterization of his conversations with Rosenstein are inaccurate.
Rosenstein ceased overseeing Mueller's probe on 7 November when Trump named Matt Whittaker acting attorney general.
In a TV interview on Sunday, former-acting Federal Bureau of Investigation chief Andrew McCabe said talks had been held in 2017 about invoking the 25th Amendment of the US Constitution that could remove a president deemed unfit.
"There is a lot of explaining to do to the millions of people who had just elected a president who they really like and who has done a great job for them with the Military, Vets, Economy and so much more".
