Does President Trump have any way out except winning this thing at this point?
I mean, he takes the AF1 to a campaign rally and makes an in-kind contribution to Loeffler and the other dude. At least that's the optics of it. Flynn got screwed for a lot less than that.
Flynn, as a part of the new admin, could talk to foreign heads of states, too. Didn't stop them from charging him with violations of Logan Act, if you remember the story. Regardless of the legality of it.
