If the investigation and report was so incredibly biased, how come it led to several people going to prison?
Fusion GPS doesn't matter because it's a stupid talking point used to distract from the facts. Yes, it was formed to throw dirt on the candidate Trump. It even started in Republican hands... The report cares about the facts, which is what matters. Those facts are what led to 34 people getting charged with several of them going to prison (many of them are Russian nationals and out of reach), among them Papadopoulos, Gates, Manafort, Flynn, Cohen, and Stone, which are hopefully names you've heard of.
High profile people with money don't go to prison unless they've committed crimes. Epstein almost got away with his numerous crimes despite all the evidence, just because of his connections and money. Thankfully justice is finally catching up to that sick person.
No matter what, Mueller is an American patriot and he's been a lifelong Republican who's now getting dirt thrown upon him because he dared to do his job. He served in the U.S. Marines and was awarded both a Bronze Star and a Purple Heart. He's respected enough by both parties that the four prior administrations ALL appointed and reappointed him to different positions.
If this country isn't going to crumble and fall, we need MORE people like Mueller who will do their jobs regardless of what political side it'll favor, or whose pockets it'll fill with money. Vilifying him means you're truly opening the door for the ones who just tell you what you want to hear rather than the truth. Once again, on both sides.
