Newly declassified documents suggest the National Security Agency stepped up domestic surveillance efforts in the weeks after 9/11, even before it received a formal directive from President Bush. On Tuesday, House minority leader Nancy Pelosi released an exchange of letters showing both the House and Senate Intelligence Committees were briefed in October 2001 about the agency’s attempts to loosen restrictions on domestic eavesdropping. However, domestic wire-taps do not appear to have occurred until President Bush ordered the secret domestic spy program in 2002.
