Striper .....who recently joined the Intel Committee out of those three you listed....I heard Orrin Hatch say this could be coming from someone who recently joined the Intel Comm.
Don't know, since I hadn't followed it before the memo became news. I do believe that Finestein is a long term member though, so that would leave the other two. And out of those two, I don't think anyone would ever think Durbin could be a traitor to the leftist cause, which if it was him would comport with Hannity's assertion that "we would be surprised...". But I still can't buy that, since any Dim Senator would be a surprise.
dc2 - Yes, that's what leads me to believe it has to be a Senator. Plus his vow to absolutely protect his source, even under threat of imprisonment.
