He shouldn’t send any representatives at all. Say it is an invalid process in which he will not participate. That’s going to be the eventual basis for the not guilty verdict anyway,so why not discredit the “trial” from the start?
He ought to send Kayleigh McAnany with her infamous binder and have her refute every bullsh!t allegation against President Trump one by one — as if the Senators were just a bunch of retards from one of her press briefings.
I don’t think Trump gives a rats bazoo about the impeachment its just a platform to present the hardcore election evidence for the public to view. He wants this in front of everyone.
