U.S. President Barack Obama has signed into law a four-year extension of parts of a controversial domestic surveillance law, just before the provisions were to expire Thursday.
The three provisions that were extended allow authorities to use roving wiretaps, conduct court-ordered searches of business records, and conduct surveillance of foreign nationals who may be acting alone in plotting attacks.
The Obama administration had urged lawmakers to extend the provisions, saying without them, the U.S. is hindered in its ability to fight terrorist attacks.
The bill’s passage in the Senate was delayed in large part because of the objections of a single senator, Kentucky Republican Rand Paul. He said the surveillance measures go too far in violating privacy rights. Other lawmakers, as well as civil liberties groups, have voiced concern about the measures.
