Why not just call the BATF guy that was sent there and ask them under oath who sent them? With the FBI being in on it, they are doubtful to do any kind of investigation. With the BATF, EPA, and OSHA all paying a visit, probably one of them will give up their boss that OK'd the trip to Houston to harass this lady. Surely there is a paper trail for the airlines with someone signing off on the plane tickets. I bet in 30 minutes I could get 30 names to call before the committee under oath. They would all know that they are in jeopardy of perjury with their gubmint pension on the line.
The "little" people will give these guys up so quick your head would spin. At some point Learner would have to give up her boss or go down herself and no immunity would be needed.
I blame the Repubs for being stuck on stupid. If Lois thinks she's safe, then go around her. What would a detective do?
Cummings is probably wired straight to Holder and the wannabe Iranian in the White House.
