House Republicans generally cast the law as a valuable asset in the war on terror. Most Democrats echoed that support but said they were concerned the law could infringe civil liberties. Following nine hours of debate, the lawmakers approved the measure 257-171.
The bulk of the back-and-forth centered on language making permanent 14 of 16 provisions that were passed after the terrorist attacks Sept. 11, 2001 and initially intended to last only 4 years.
The bill also gave a 10-year extension to two provisions — one allowing roving wiretaps and another allowing searches of library and medical records — that triggered passionate arguments between Democrats and Republicans.
CBS News Correspondent Joie Chen reported that some Democrats warn these provisions give the government too broad a reach, but President Bush disagrees.
"This is no time to let our guard down, and no time to roll back good laws," Mr. Bush said.
The Patriot Act moved forward in the Senate as well, as the Judiciary Committee unanimously approved changes Thursday and sent the measure to the floor for a vote. The changes, agreed to after all-night negotiations, include a provision that requires law enforcement to report within seven days of a search warrant being granted whether there was enough evidence to justify the search.
The panel also deleted a provision requiring law enforcement agencies to report on wiretaps in a way they found onerous.
A competing bill also has been approved by the Senate Intelligence Committee, which would give the FBI expanded powers to subpoena records without the approval of a judge or grand jury. That ensures further Senate talks on the terrorism-fighting measure.
While civil libertarians have expressed concern about the original law, passed by Congress just 45 days after the Sept. 11 attacks, congressional and Justice Department advocates argue it has accelerated the pursuit and prosecution of suspected terrorists by breaking down barriers between law enforcement and intelligence agencies.
