Trump probably knows already
Trump has a history of revealing a LOT of things other presidents won't. He's big on transparency. He gets briefings and PROBABLY KNOWS ALREADY, but speaks carefully as he's not in office yet (so it might be a crime to "confirm or deny"). But he CAN say a lot, if it SOUNDS like an opinion.
Imagine the Trump admin NOT getting to the bottom (once and for all) of the Kennedy assassinations from the 60's, with RFKJr. as a member of his cabinet... you KNOW this is getting revealed if there's something to find. THAT and a zillion OTHER conspiracies. No need for tinfoil hats. "Deep State" is already on notice. Truth.
