WASHINGTON — The National Security Agency is facing renewed scrutiny over the extent of its domestic surveillance program, with critics in Congress saying its recent intercepts of the private telephone calls and e-mail messages of Americans are broader than previously acknowledged, current and former officials said.
The agency’s monitoring of domestic e-mail messages, in particular, has posed longstanding legal and logistical difficulties, the officials said.
Since April, when it was disclosed that the intercepts of some private communications of Americans went beyond legal limits in late 2008 and early 2009, several Congressional committees have been investigating. Those inquiries have led to concerns in Congress about the agency’s ability to collect and read domestic e-mail messages of Americans on a widespread basis, officials said. 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.
Both the former analyst’s account and the rising concern among some members of Congress about the N.S.A.’s recent operation are raising fresh questions about the spy agency.
Representative Rush Holt, Democrat of New Jersey and chairman of the House Select Intelligence Oversight Panel, has been investigating the incidents and said he had become increasingly troubled by the agency’s handling of domestic communications.
In an interview, Mr. Holt disputed assertions by Justice Department and national security officials that the overcollection was inadvertent.
“Some actions are so flagrant that they can’t be accidental,” Mr. Holt said.
Other Congressional officials raised similar concerns but would not agree to be quoted for the record.
Mr. Holt added that few lawmakers could challenge the agency’s statements because so few understood the technical complexities of its surveillance operations. “The people making the policy,” he said, “don’t understand the technicalities.”
The inquiries and analyst’s account underscore how e-mail messages, more so than telephone calls, have proved to be a particularly vexing problem for the agency because of technological difficulties in distinguishing between e-mail messages by foreigners and by Americans. A new law enacted by Congress last year gave the N.S.A. greater legal leeway to collect the private communications of Americans so long as it was done only as the incidental byproduct of investigating individuals “reasonably believed” to be overseas.
But after closed-door hearings by three Congressional panels, some lawmakers are asking what the tolerable limits are for such incidental collection and whether the privacy of Americans is being adequately protected.
“For the Hill, the issue is a sense of scale, about how much domestic e-mail collection is acceptable,” a former intelligence official said, speaking on condition of anonymity because N.S.A. operations are classified. “It’s a question of how many mistakes they can allow.”
While the extent of Congressional concerns about the N.S.A. has not been shared publicly, such concerns are among national security issues that the Obama administration has inherited from the Bush administration, including the use of brutal interrogation tactics, the fate of the prison at Guantánamo Bay, Cuba, and whether to block the release of photographs and documents that show abuse of detainees.
In each case, the administration has had to navigate the politics of continuing an aggressive intelligence operation while placating supporters who want an end to what they see as flagrant abuses of the Bush era.
The N.S.A. declined to comment for this article. Wendy Morigi, a spokeswoman for Dennis C. Blair, the national intelligence director, said that because of the complex nature of surveillance and the need to adhere to the rules of the Foreign Intelligence Surveillance Court, the secret panel that oversees surveillance operation, and “other relevant laws and procedures, technical or inadvertent errors can occur.”
“When such errors are identified,” Ms. Morigi said, “they are reported to the appropriate officials, and corrective measures are taken.”
