Bears repeating, for the "Trump can fire him anytime!" crowd.
Trump has the authority to fire Rosenstein as well as Sessions. Too bad for the “Grassley has Trump by the short hairs” rumor mongers.
From the WaPo Feb 2nd 2018:
“As president, Trump can fire people who work in the executive branch for whatever reason he wants. Take FBI Director James B. Comey, whom Trump fired in May because of, he said, this Russia thing.
” When reporters asked him point blank Friday in the Oval Office whether he was going to fire Rosenstein, Trump responded cryptically: You figure that one out.
