Capping months of partisan wrangling, the US Senate gave final congressional approval on Thursday to renewing the USA Patriot Act, which expanded the government's power to track down foes in the war on terrorism.
A day after passing a related bill to better protect civil liberties under the act, the Senate endorsed the overall measure 89-10. It next goes to President George W. Bush to sign into law. The House of Representatives passed it in December.
First enacted shortly after the September 11 attacks, the Patriot Act broadened the ability of the US government to obtain private records, conduct wiretaps and searches and share information.
Fierce debate over the act's renewal has pitted critics who say its provisions have infringed too much on basic rights against backers who say such measures are essential to safeguard America against further attacks.
With 16 provisions of the act set to expire next week, the bill would make 14 of them permanent and extend two others by four years.
