Not necessarily that they are being surveilled, I took A Citizen Reporter's comments as that the Senators "suspicions" about the program also makes them appear like they are targets.
I disagree with that - I think honest suspicion as a matter of principle is healthy. OTOH, Durbin and Schumer's attacks are politically motivated and not aimed at finding a way to balance a number of competing interests.
Well, then let me leave it that many of these Senators have done enough in the past to make me have an honest suspicion as to their character and behavior.
