You obviously don't know that the NSA is an agency of the US DoD, and that falls under the Joint Chiefs of Staff, and their mission was set forth by Executive Order 12333.
In case you were not paying attention, this all stems from Bush's "President's Surveillance Program".
So since this is the NSA's responsibility, and its headed by someone appointed during the Bush Administration, and according to you an executive order by Reagan, what does this have to do with Obama?
