I’m not at all surprised that Attorney General William Barr told the Senate that there may have been some “spying” during the 2016 campaign. After all, he was hired by Trump to follow up on the right-wing nutsery claims about the Democrats doing it, and although he has no offer of proof, he basically echoed what Trump as been screaming about all along.
The fact that the FBI and other intelligence agencies may have had legitimate reasons to investigate the glaring clues that a foreign hostile power was trying to interfere with the electoral process doesn’t matter. All these conspiracy whacks hear is “spying” and they’re over the moon. Now the emboldened GOP will say “There should never have been an investigation of anybody at all!” That’s tantamount to saying, “Yeah, it was fine with me if the Russians wanted to put Trump in office.”
Trump got the attorney general he really wanted in William Barr: a yes-man who does his bidding.
