    February 12, 2003 - The ACLU, along with a coalition of other civil liberties groups, asks the Supreme Court to overturn new, more lenient standards for wiretaps in foreign intelligence investigations.

Leaders in the United States Congress have been briefed more than a dozen times on this program. And it has been effective in disrupting the enemy while safeguarding our civil liberties. This program has targeted those with known links to al-Qaida. I've reauthorized this program more than 30 times since September the 11th attacks, and I intend to do so for so long as the nation faces the continuing threat of an enemy that wants to kill our American citizens."
