"The testimony from Trump’s White House chief of staff could change everything"

Um, no, I really don't think that blatant crimes committed by Meadows on behalf of an even bigger criminal (i.e. Trump) should be considered as "part of his official government duties."[1]

Really, this is nothing more than a flagrant ploy to try to get the trial moved up to a federal case, for which Trump could then potentially just pardon everyone involved if he became President again (which is one reason, among myriad other reasons, why Trump should never become President again). As it stands now, as a state court case rather than a federal one, any Presidential pardon powers that Trump could potentially regain do not apply, which is a very strong reason why it should not be bumped up to federal court. If the judge falls for it and lets it be bumped up to federal court, then that is just one step closer to Trump and Trump's fellow criminals yet again managing to slither their way out of any meaningful consequences, similar to most of the rest of Trump's entire fucking, goddamned life up to this point.
