Remember what Q said.  Optics are the most important thing in DC.  By Trump ordering the FBI to investigate, which I am sure they have already done and unofficially told him what they were going to do, he has completely disarmed the Dems.  If McConnel says that the Senate will proceed with the vote regardless of the FBI conclusions then it's on McConnel and not Trump.  Trump has washed his hands on this and neither the MSM nor the Dems can pin it on him.    It's actually a rather clever move and do remember to whom FBI's Wray answers, RR. And we all know that RR is in a precarious situation right now; to say the least.    It's a well executed strategy
