Its impossible because once the president does it is no longer classified. He’s at the top of the classification hierarchy
The New York Times and WaPo are trying to mislead their readers by implying trump revealed highly classified info to a Russia diplomat. here is the archived article
It’s bullshit though. It’s nothing out of the ordinary for that to happen. The president is allowed to do this. The issue with Hillary Clinton was she’s not the president and she doesn’t have the authority to do it
The president has the right to know all and declassify whatever he likes. This is affarimed in Department of Navy v. Egan, 484 US 518 (1988)
He is the head of the military. If the head of the military doesn’t have full intelligence authority then what is the point
The president also has the authority to discuss classified information with foreign diplomats
Let’s look at the Cuban missile crisis. The whole thing was sparked by the US placing missiles in turkey that could hit Moscow. This left the Russians at a disadvantage because we could wipe them out before they could respond and hit us. So in response they placed missiles in Cuba. The whole thing was deescalated by an agreement that we move our missiles out of turkey and they move theirs out of Cuba. The US public didn’t know this though and many still don’t. Those missiles and their capabilities were classified. Still, in order to even have the discussion JFK would’ve had to have discussed highly classified material with Nikita Kruschev
It is normal for a president to do this. Almost every single one has done it. They have to do it many times when talking with other countries.
The NYT and WaPo are being deliberately dishonest here when they write a story like this and the only reason they’re doing it is to imply that trump is using his position to give the Russians US secrets. That isn’t true but they can sure imply it. This is done to mislead their readers and cause faux outrage in people who are ignorant of the thing they’re pissed off about to begin with
Let’s not even get into the fact that they’re writing the article based on “anonymous White House source” which means “my ass” to them.
The details of the presidents private conversations with other state representatives are classified though so if this was a private meeting and someone leaked that to wapo then THAT would be illegally leaking classified information.
