I agreed with Duncan Hunters comment of making sure such deals would not effect national security. Idealy, I think this should be done on the executive level not congressional. It's supposed to be set up that way now but does not seem to work as intended. Hunter wants more input from DOD and Homeland security. Meaning, to me, they should be able to kill a deal if they believe it's in the nations interest. Since both agencies have congressional oversight now anyway, it's not much of a change in proceedure as much as a change in emphasis. At least, that's how I understood what he was saying.
This amounts to more of a tightening up of the process, as opposed to changing it that much.
Never, ever, put business deals in the hands of congress. There is too much of a temptation to help friends or hurt enemies, as we've seen all too often in the past.
