Donald Trump has spent the better part of the last seven years calling into question the legitimacy of the legal system. He has repeatedly labeled scrutiny of him and his allies unfair and decried convictions of his allies, culminating in a remarkably partisan record on pardons. He has wielded the phrase “witch hunt” and “hoax” many hundreds of times. He has attacked judges, juries, prosecutors and investigators, in one case drawing a rebuke from his own Supreme Court nominee.
