President Bush has vowed to keep steady pressure on members of the al Qaida terrorist group.
Mr. Bush on Thursday delivered the latest in a series of speeches ahead of the fifth anniversary of the September 11th attacks and key congressional elections in November.
Speaking in Atlanta, Mr. Bush billed his third terrorism speech in three days as a progress report on steps the country has taken to protect itself. He called on Congress to authorize his administration to monitor international phone calls and e-mails without a search warrant.
A federal court ruled last month that such a practice is unconstitutional.
Democrats tried to counter Mr. Bush's speech by proposing new legislation they say will improve U.S. security by changing course in Iraq, providing better tools to bring terrorists to justice, and implementing recommendations from the 9-11 investigative commission for strengthening national security.
Democrats accuse Mr. Bush of emphasizing anti-terror efforts to distract from the increasingly unpopular war in Iraq. They hope the Iraq issue will help them wrest control of one or both Houses of Congress in November elections.
On Wednesday, Mr. Bush acknowledged for the first time that agents with the CIA had interrogated terror suspects at secret overseas locations. He also said 14 of those suspects are now at the U.S. military detention facility at Guantanamo Bay, Cuba.
In the same speech, Mr. Bush urged Congress to approve the creation of military commissions to try the detainees. The government considers them "enemy combatants."
European Union officials are demanding that the locations of the CIA detention centers be made public.
