Trump has continuously let the FBI and DOJ delay and obfuscate the release of documents. Way past time for trump to pit sessions out to pasture and hire someone who will actually clean house.
I sure hope Trump doesn’t think he is stuck on the horns of a dilemma on this, one horn being letting Mueller go on and eventually stumble onto something (no matter how minor) or fire him and deal with the outcry.
Honestly, myself, I think he should have fired Mueller back in February at the latest.
