My guess is the names were leaked by friendlies. At first I figured they were outed by the Scumbag Administration - - with the delicious irony of using Fox News to handle the dirty work - - but then I figured no way would Fox News be stupid enough to fall for such an obvious skunk job.
Their names were known by Issa and members of the committee and select members of their staff ... surely they couldn’t have kept those names away from Issa for an extended period of time.
At least in theory.
The regime may be working to dissolve their opposition as they perceive it. These three may not actually be the whistleblowers, but the regime wants these out of their way and can use the ‘leak’ to try and out the actual folks who would come forward. it is a form of witness intimidation, and this thugocracy og little barry bastard boy and his hench goons use ‘The Chicago Way’ to a high degree.
