And what was the thinking then behind appointing Rosenstein?
I think Tenpas and RR were pals at one time.
Before this all started, RR was known as a Republican (although an East Coast liberal one) and was actually a Federalist Society member, at least at one time. And one of few prosecutors who has put Democrat politicians in jail.
No reason to doubt his cred until recently, although prosecutors are bound to have enemies.
