What are you getting at? As far as I know, OMB doesn't require key escrow, so it almost certainly doesn't happen at scale. I'd imagine that if an intelligence service asked an agency for keymat, they'd happily provide it. I know that I wouldn't have a problem with someone from old St. Elizabeths Hospital or Fort Meade or Crystal City asking me for stuff, especially since the order to co-ooperate with DHS or NSA or the Pentagon would come through the agency's chain of command.
That said, DHS runs an intrusion prevention system called EINSTEIN, whose mission is to protect all federal civilian computer networks:
Using EINSTEIN _is_ mandated by OMB, so if you're worried about the U.S. federal government snooping on your communications with the U.S. federal government, I don't know what to tell you.
