If this was a problem for the country, wouldn't it be DHS's job? And if there was an issue to be looked in to, it's FBI's job. And if there is something about spying to figure out if someone is doing something, there is the CIA and the NSA depending on where they need to look?
On top of that: wouldn't this be something that should simply be looked at internally at agencies and if there is an actual problem, resolve it for the country by issuing a law or directive or bill or whatever name they put to rules the US-based companies have to follow?
