Members of Congress do not trust that the House Intelligence Committee is providing the necessary oversight.

I've requested classified information, and further meetings with NSA officials. The House Intelligence Committee has refused to provide either. Supporters of the NSA's vast ubiquitous domestic spying operation assure the public that members of Congress can be briefed on these activities whenever they want. Senator Saxby Chambliss says all a member of Congress needs to do is ask for information, and he'll get it. Well I did ask, and the House Intelligence Committee said "no", repeatedly. And virtually every other member not on the Intelligence Committee gets the same treatment.
