Two judges on the secretive court that approves warrants for intelligence surveillance were told of the broad monitoring programs that have raised recent controversy, a Republican senator said, connecting a court to knowledge of the collecting of millions of phone records for the first time. President George W. Bush, meanwhile, insisted Tuesday the government does not listen in on domestic telephone conversations among ordinary Americans. But he declined to specifically discuss the compiling of phone records, or whether that would amount to an invasion of privacy. USA Today reported last week that three of the four major telephone companies had provided information about millions of Americans' calls to the National Security Agency. However, Verizon Communications Inc. denied on Tuesday that it had been asked by the agency for customer information, one day after BellSouth said the same thing.
