President Donald Trump mocked former FBI director James Comey in a Thursday tweet for concurring with a Justice Department inspector general report finding Andrew McCabe guilty of lacking candor.

James Comey just threw Andrew McCabe “under the bus.” Inspector General’s Report on McCabe is a disaster for both of them! Getting a little (lot) of their own medicine? — Donald J. Trump (@realDonaldTrump) April 19, 2018

Comey told CNN’s Jake Tapper in a Thursday afternoon interview that “given that the IG’s report reflects interactions that Andy McCabe had with me and other senior executives, I could well be a witness.”

The former FBI director concurred with the inspector general report, saying, “It is not acceptable in the FBI or the Justice Department for people to lack candor. It’s something we take really seriously.”

The report finding McCabe guilty of lack of candor led to a referral from the Department of Justice to the U.S. attorney of the District of Columbia for possible criminal prosecution. McCabe and his attorneys believe he will not be prosecuted.
