You have things half assed backwards, dave.
Its up to the Libs to prove Trump guilty, not for Trump to prove himself innocent. And even it was, there is nothing that Mr. Bolton could say that would convince extreme doofuses like Pocahontas and Crazy Bernie that Trump is a tremendous President who is worthy to rule over the nation he loves.
he could have prevented the charges, the articles of impeachment, from even happening,
if he was innocent he would have shown something, anything at all that would have discredited the accusations.... like any normal human being, innocent of accusations, would have presented to the cops before they were charged... that could exculpate them, before those charges are drawn.
Makes ya wonder, did Trump want this impeachment for some perverted political gain?
OR, is he really not as innocent and perfect, as he claims to you Trumpettes?

The R's do not want a trial, where the prosecution has to provide their case, beyond a reasonable doubt, that the defendant is guilty.
There is no other way to view it.
Ya'll seem to want a SHAM trial, where the FIX IS IN, before prosecutors even present their witnesses and evidence.
