Actually, GOP members of the House sent him a letter asking him to re-examine the issue. The person specifically behind it was, of course, Nunes.
What's interesting about it is that 1) Sessions specifically testified before Congress that he would recuse himself from any investigations of Clinton or Trump. Thus, by writing this letter, he has proven that he committed perjury and he must resign and possibly be prosecuted (I laugh, because its about the tenth time Sessions has committed perjury;
and 2) Nunes is part of a small group of GOP Congressmen holding secret meetings (itself a violation of federal law) to try to undermine the DOJ and the FBI.
Words you can't use at CDC. Threatening UN members over today's meaningless vote on recognizing the capital of Israel. Trump himself tweeting that he's going to take over the FBI and rebuild it. Secret GOP meetings of Congress to go after the FBI and the DOJ. Trump firing those who do not promise to do his bidding.
And you idiots thought Obama was authoritarian.
