The leak, in fact, is legal until otherwise determined to be illegal.
Jim Himes said it was illegal. Are you saying a Democrat member of the House Intel committee is wrong?
Of course he could be wrong. Hell, in that same interview, he said the leak stemmed from the White House after they were informed that Flynn was in communication with Russians and could be blackmailable.
And that's wrong because the leak first appeared in the Washington Post prior to that.
But it's cute watching your brain spin. You actually thought because he's a Democrat, I would take his word as gospel.
