:lol: oh, wow, Politifact.
Hey, how about I cite Sean Hannity to prove that Obama committed treason?
Yeah. "Rumors of US involvement" =/= a government official saying "This was a joint-US Israeli effort, and here is the unit name of the Israelis involved".
There are rumors of
lots of classified stuff. For example, there are lots of rumors (including many claims by ISIS and others) that the Israelis have penetrated a number of organizations. Confirming them when you don't have the authority to do so is still a violation of the Espionage Act.
Or, in these two cases,
not a violation of said act, because the individual who decided to release that information had the authority to do so.
This is unfortunately incorrect, as the Poles can attest. We hoped to have Russia on board helping to pressure Iran to come to a deal with us, and so we gave up the missile defense shield in Eastern Europe, hoping that would engender positive feelings about us, and bring them on board. Even after that failed, Obama was (rather famously) promising them more flexibility after his re-election, and mocking Romney for claiming Russia was a threat.
W. Bush, Obama, and now Trump have all come into office thinking they can make sweet deals with Putin and get stuff done. For Bush, the realization this was false came in his second term. For Obama, it appears to have come after Hillary lost the election. I have no idea if there will be a point where it will come for Trump, but I would bet it would require a sense on his part that he'd been personally insulted or cut off.
Which is irrelevant, since the question is whether or not the POTUS has the authority to de or reclassify information at will. He does, and he can, and Presidents have regularly done so, for various reasons.
Exactly. The President is authorized to do with Classified Information
whatever he deems to be in the interests of the United States.* If Trump decided we were better off with him impressing the Russians with how smart he was, and chose to share classified information in order to accomplish that - well, I think it's a moronic and dangerous decision, but it is also fully within his authority to do. If America doesn't like having a security risk for POTUS, then America shouldn't have put up two candidates who were both security risks for the office.
*with one notable exception having to do with initiating covert actions.
That's right, and that is also his prerogative.
Precedent is a legal question - there are plenty of precedents of US Presidents' of both parties declassifying information, including information that wasn't technically ours, but rather given to us by allies.
