President Barack Obama signed into law Saturday a one-year extension of several surveillance provisions included in the Patriot Act.
The House approved the bill 315-97 on Thursday, a day after the extension passed the Senate.
The provisions, including roving wiretaps, records access and tracking terror suspects not affiliated with any group, were set to expire on Sunday. Democrats opposing the extension were unable to add desired civil-liberties protections.
The Patriot Act was first passed by Congress after the Sept. 11, 2001, attacks as a defense mechanism against terrorists.
