NSA spying flap extends to contents of U.S. phone calls

Rep. Jerrold Nadler, a New York Democrat, disclosed on Thursday that during a secret briefing to members of Congress, he was told that the contents of a phone call could be accessed "simply based on an analyst deciding that."

If the NSA wants "to listen to the phone," an analyst's decision is sufficient, without any other legal authorization required, Nadler said he learned. "I was rather startled," said Nadler, an attorney and congressman who serves on the House Judiciary committee.

There are serious "constitutional problems" with this approach, said Kurt Opsahl, a senior staff attorney at the Electronic Frontier Foundation who has litigated warrantless wiretapping cases. "It epitomizes the problem of secret laws."
