I have no idea what DHS's numbers are, but the relevant subcommittees in both the House and Senate should have been notified of any major reprogramming, and ultimately the Congress would have to approve an expansion. Unless it is entirely lawless ... not that I expect the courts to enforce anything againt this crowd.
I don’t know about the manning in CIS. It seems extreme to hire 1000 new employees even if you wanted to process these requests. What is the rest of CIS doing. They never hired a 1000 more doctors for the VA., but then again Vets don’t usually vote democrat party.
