The Senate on Wednesday extended for a year key provisions of the nation’s counterterrorism surveillance law that are scheduled to expire at the end of the month. One provision authorizes court-approved roving wiretaps that permit surveillance on multiple phones. A second allows court-approved seizure of records and property in antiterrorism operations. A third permits surveillance against a noncitizen suspected of engaging in terrorism who may not be part of a recognized terrorist group. In agreeing to pass the bill, Senate Democrats retreated from adding new privacy protections to the USA Patriot Act. The Senate approved the bill on a voice vote with no debate. It now goes to the House.
