The President of the United States is more than just a government official and no, no President has ever had his house raided by the Nazis in our history. Yes, the judge should have recused himself because he had a bias against Trump for some time and that's well documented. Any judge that has a hatred of the person in a case he's asked to handle is obligated to recuse themselves.
I never said the FBI was obligated to allow oversight, but disallowing it raises a lot of questions if they claim to have found something in Mar-A-Lago Trump claims he never had. The FBI has been corrupt at least since the DumBama administration.
It has everything to do with the President running again: two phony impeachments, a 30 million dollar phony Russian collusion investigation, trying to sick the NYC commies on Trump, the bogus so-called 1/6 investigation, and now this. All by design to try and stop Trump from running again.
