Bush urges passage of bill to overhaul spy power

The president maintains he acted legally, saying he had the wartime power to authorize the program. He put it under FISA jurisdiction in January 2007. Terms remain secret.

The bill would replace a temporary law that expired in February that had expanded U.S. power to conduct warrantless surveillance. The measure would require FISA court approval of U.S. procedures in monitoring phone calls and e-mails. (Editing by David Storey and Philip Barbara)
