WASHINGTON — The Central Intelligence Agency is secretly collecting bulk records of international money transfers handled by companies like Western Union — including transactions into and out of the United States — under the same law that the National Security Agency uses for its huge database of Americans’ phone records, according to current and former government officials.
The C.I.A. financial records program, which the officials said was authorized by provisions in the Patriot Act and overseen by the Foreign Intelligence Surveillance Court, offers evidence that the extent of government data collection programs is not fully known and that the national debate over privacy and security may be incomplete.
Some details of the C.I.A. program were not clear. But it was confirmed by several current and former officials, who spoke on the condition of anonymity because the matter is classified.
The data does not include purely domestic transfers or bank-to-bank transactions, several officials said. Another, while not acknowledging the program, suggested that the surveillance court had imposed rules withholding the identities of any Americans from the data the C.I.A. sees, requiring a tie to a terrorist organization before a search may be run, and mandating that the data be discarded after a certain number of years. The court has imposed several similar rules on the N.S.A. call logs program.
Several officials also said more than one other bulk collection program has yet to come to light.
“The intelligence community collects bulk data in a number of different ways under multiple authorities,” one intelligence official said.
Dean Boyd, a spokesman for the C.I.A., declined to confirm whether such a program exists, but said that the agency conducts lawful intelligence collection aimed at foreign — not domestic — activities and that it is subject to extensive oversight.
“The C.I.A. protects the nation and upholds the privacy rights of Americans by ensuring that its intelligence collection activities are focused on acquiring foreign intelligence and counterintelligence in accordance with U.S. laws,” he said.
Juan Zarate, a White House and Treasury official under President George W. Bush, said that unlike telecommunications information, there has generally been less sensitivity about the collection of financial data, in part because the government already collects information on large transactions under the Bank Secrecy Act.
“There is a longstanding legal baseline for the U.S. government to collect financial information,” said Mr. Zarate, who is also the author of “Treasury’s War,” about the crackdown on terrorist financing. He did not acknowledge the C.I.A. program.
Orders for business records from the surveillance court generally prohibit recipients from talking about them. A spokeswoman for one large company that handles money transfers abroad, Western Union, did not directly address a question about whether it had been ordered to turn over records in bulk, but said that the company complies with legal requirements to provide information.
“We collect consumer information to comply with the Bank Secrecy Act and other laws,” said the spokeswoman, Luella Chavez D’Angelo. “In doing so, we also protect our consumers’ privacy.”
In recent months, there have been hints in congressional testimony, declassified documents and litigation that the N.S.A. program — which was disclosed by Edward J. Snowden, a former N.S.A. contractor — is not unique in collecting records involving Americans.
For example, the American Civil Liberties Union is fighting a Freedom of Information Act lawsuit for documents related to Section 215 of the Patriot Act, the provision that allows the government to compel companies to turn over business records for counterterrorism purposes. After the government declassified the N.S.A. phone records program, it has released many documents about it in response to the suit.
But the government has notified the A.C.L.U. that it is withholding two Foreign Intelligence Surveillance Court rulings invoking Section 215 — one dated Aug. 20, 2008, and the other Nov. 23, 2010 — because they discuss matters that remain classified, according to Alexander Abdo, an A.C.L.U. lawyer. “It suggests very strongly that there are other programs of surveillance that the public has a right to know about,” Mr. Abdo said.
