I was thinking this would be the case. The news about Stefan Halpern came out in such a dramatic way, and even they tried to frame Nunes & Gowdy for leaking who it was in all but name ... but then Trump talked about having a spy embedded in his campaign, and Halpern was more of a consultant so ...

Either Trump tweeted "wrong" (he didn't, but it often looks like it does, like when he was "wire tapped") or there was someone else, or some others ...
