President Trump directed his Attorney General Jeff Sessions to end special counsel Robert Mueller's Russian collusion investigation on Wednesday, which he still believes is a "witch hunt." He also suggested the investigation is politically biased. Trump sent his AG the directive after quoting liberal lawyer Alan Dershowitz on Twitter.

“FBI Agent Peter Strzok (on the Mueller team) should have recused himself on day one. He was out to STOP THE ELECTION OF DONALD TRUMP. He needed an insurance policy. Those are illegal, improper goals, trying to influence the Election. He should never, ever been allowed to........ — Donald J. Trump (@realDonaldTrump) August 1, 2018

.....remain in the FBI while he himself was being investigated. This is a real issue. It won’t go into a Mueller Report because Mueller is going to protect these guys. Mueller has an interest in creating the illusion of objectivity around his investigation.” ALAN DERSHOWITZ.... — Donald J. Trump (@realDonaldTrump) August 1, 2018

..This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA! — Donald J. Trump (@realDonaldTrump) August 1, 2018

Sessions has actually recused himself from the probe, so it would likely be up to Deputy AG Rod Rosenstein to make a decision on whether the investigation will proceed.

Top Republicans like House Speaker Paul Ryan have defended the Mueller probe and suggested it should go on unimpeded. Mueller should be allowed to do his job, Ryan said this spring.
