Far from the neutral law enforcement agency it perhaps used to be, today's FBI operates almost solely as a political weapon to punish Republicans who veer too far from the script.
Take Rep. Matt Gaetz (R-Fla.) as one recent example. The FBI is now investigating him for allegations that he had sexual relations with a 17-year-old girl whom he allegedly paid to travel with him. The Biden Crime Family, meanwhile, is not under any investigation at all for its litany of not only criminal but treasonous behavior.
The FBI also infamously went after Donald Trump and his campaign back in 2016 for the "Russian collusion" conspiracy, which was quickly determined to be a hoax. No proper investigation was ever conducted into the Clinton Crime Cartel, though.
