Day Four of FBI Director James Comey hiding out in an undisclosed location.
I've seen what Comey's FBI has done in the presidential election before on a local level. A district attorney opposing a candidate for city council opens a extremely public investigation of that candidate. After the election is over, that investigation is very, very quietly dropped.
It is a sleazy and corrupt use of the office for blatantly political purposes but it frequently has the desired effect of defeating the candidate in question.
Say what you will about J. Edgar Hoover, how he used the dossiers he compiled on politicians to blackmail them into doing what he wanted, but Hoover never demeaned the Bureau by obviously and unscrupulous trying to influence the outcome of an election. Hell, even Top Cop Heinrich Himmler never did that.
