Trump should consider his #1 accomplishment to be firing James Comey. That was the act of a great man. James Comey was a terrorist in the guise of a litigator, bent on destroying the freedom of every American. He imprisoned elderly women who bake cookies for a living for fun. He wanted to turn every iPhone owner in the world into the prospective criminals under eternal surveillance.
The FBI is just a generally shitty authoritarian organization. It does shitty things. Thankfully, it is no longer run by the international terrorist overlord James Comey. I am quite enjoying Trump taking the FBI down a peg. It's even more funny considering the FBI is notoriously conservative and supported Trump from the start, LOL.
