President Obama on Friday signed into law a bill that extends three Patriot Act surveillance authorities until late May. Obama signed the "FISA Sunsets Extension Act of 2011," which refers to the Foreign Intelligence Surveillance Act. Surveillance authorities under that act were extended in part by amending the USA Patriot Improvement and Reauthorization Act. With Obama's signature, the ability of the United States to access business records, conduct roving wiretaps and monitor individual terrorists is maintained until May 27. The administration has said it supports a longer extension, and the Senate next week will begin working on a three-year extension.
