I actually called my two (deeply red) senators' offices about this issue yesterday. I respectfully urged them to support the investigation that their own colleagues (McCain, Graham, McConnell) are calling for. I mean ... this is important (serious, scary, etc.), folks. Talked to staffers, of course. One took my comments. The other explained that the FBI and CIA have to get on the same page about it, then Congress will act accordingly. Fair enough.
I urge the smart, articulate Mutants herewith to do the same about this -- and other issues you care about. It was incredibly quick and easy, and I've got to think that the weight of calls and emails to our representatives will have impact over time.
