I certainly get the yapping dog analogy. Reminds me of Trey Gowdy "going after" hillary.
But....if nothing else, Wray is going to be tied up for an extended period of time and is going to incur significant legal bills "defending" himself. Lawfare 101, which the dems have been practicing against Conservatives for at least a decade.
It will send a message to the dems/"progressives"/commies that they will be subjected to the same "tactics" that conservatives have and that even if they never go to trial, they will suffer the same fate as Roger Stone, Rudy Giuliani, Mike Flynn, Steve Bannon. Maybe it'll slow them down. Maybe not, we'll see.
Fuck 'em, have at it !
