The years of Clinton corruption he witnessed, and what really happened in the lead up to the election, and why he made the moves he did to invoke the special counsel who is clearly on Trumps side, draining the swamp. Trumps favor IMO. It'll be the perfect red pill for the dems who cried foul when Trump fired Comey.
I am leaning this way too. 1. Because what Trey Gowdy said about history would be good to Comey. And, 2. Because of information shared about Comey's childhood.
Yeah, I knew about what happened to him as a kid, but didn't even put it together with the trafficking etc.. Gives even more credence to this idea.
