(Sec. 12) Requires reports through 2009, from the Director of the National Security Agency (NSA) to the intelligence committees, on the effectiveness and use of minimization procedures applied to information concerning U.S. persons acquired by means that were considered electronic surveillance before the enactment of this Act but no longer constitute electronic surveillance as of this Act's effective date.
