James Risen and Eric Lichtblau report today that Congress is once again becoming concerned that the NSA is intercepting domestic email messages without a warrant:
Supporting that conclusion is the account of a former N.S.A. analyst who, in a series of interviews, described being trained in 2005 for a program in which the agency routinely examined large volumes of Americans’ e-mail messages without court warrants. Two intelligence officials confirmed that the program was still in operation.
....He said he and other analysts were trained to use a secret database, code-named Pinwale, in 2005 that archived foreign and domestic e-mail messages. He said Pinwale allowed N.S.A. analysts to read large volumes of e-mail messages to and from Americans as long as they fell within certain limits — no more than 30 percent of any database search, he recalled being told — and Americans were not explicitly singled out in the searches.
There's also this:
The N.S.A. is believed to have gone beyond legal boundaries designed to protect Americans in about 8 to 10 separate court orders issued by the Foreign Intelligence Surveillance Court, according to three intelligence officials who spoke anonymously because disclosing such information is illegal. Because each court order could single out hundreds or even thousands of phone numbers or e-mail addresses, the number of individual communications that were improperly collected could number in the millions, officials said.
....Overcollection on that scale could lead to a significant number of privacy invasions of American citizens, officials acknowledge, setting off the concerns among lawmakers and on the secret FISA court. “The court was not happy” when it learned of the overcollection, said an administration official involved in the matter.
Rep. Rush Holt (D–NJ), chairman of the House Select Intelligence Oversight Panel is investigating. "Some actions are so flagrant that they can't be accidental," he says.
