During the week of Feb. 11, the White House and Democrats in Congress exchanged blows over whether and how to extend the surveillance powers of the Protect America Act of 2007 (PAA). The Senate's approach, the FISA Amendments Act (S. 2248), included a provision granting immunity for telecommunications companies that helped the government monitor citizens through its warrantless wiretapping program. The House leadership, opposed to immunity for telecommunications companies, refused to consider the bill. Instead, House leaders wanted to pass a three-week extension of PAA powers to give themselves time to resolve differences with the Senate, but House Republicans blocked the move. As a result, the PAA expired at midnight Eastern time on Feb. 16. Despite the expiration, the government still has numerous surveillance tools available as debate continues.
