Donald Trump praises Comey in October 31, 2016 - "It took a lot of guts" for Comey to bring new evidence to light on Hillary Clinton emails. Now Comey's a criminal to Trump.
That's Trump in a nutshell. If you hurt an opponent of his, you get praise and protection. If you hurt him, you get criticism and attacks. It's the same Comey -- a guy trying to do his job. And it's the same Trump -- a guy who doesn't care about the rule of law, it's 100% expediency for him and 0% respect for honesty and fair play.
As a side note, criminals are paying $$$$ to lobbyists, to get their cases in front of Trump. The man who has pardons for sale is calling Comey a criminal ... that's rich. So to speak.
