There is an old saying, "loose lips sink ships" and "a need to know" both apply in this case. Just because a person is on a congressional committee such as the Homeland Security Committee does not mean they necessarily have a need to know. Especially since many of these people are leaking information out.
I agree completely, a few convictions of treason might tighten up some of those lips.
While I agree, I hate to jump to conclusions that he would want it for those reasons, but do agree that not everybody needs access to that sort've confidential info.
And you guys can GUESS my views on treason...
