What exactly STELLARWIND did has never been disclosed in an unclassified form. Which parts of it did Comey approve? Which did he shut down? What became of the programs when the crisis passed and Comey, now Obama’s expected nominee for FBI director, returned to private life?
Authoritative new answers to those questions, drawing upon a classified NSA history of STELLARWIND and interviews with high-ranking intelligence officials, offer the clearest map yet of the Bush-era programs and the NSA’s contemporary U.S. operations.
STELLARWIND was succeeded by four major lines of intelligence collection in the territorial United States, together capable of spanning the full range of modern telecommunications, according to the interviews and documents.
Foreigners, not Americans, are the NSA’s “targets,” as the law defines that term. But the programs are structured broadly enough that they touch nearly every American household in some way. Obama administration officials and career intelligence officers say Americans should take comfort that privacy protections are built into the design and oversight, but they are not prepared to discuss the details.
The White House, the NSA and the Office of the Director of National Intelligence declined to comment on the record for this article. A senior intelligence official agreed to answer questions if not identified.
“We have rich oversight across three branches of government. I’ve got an [inspector general] here, a fairly robust legal staff here . . . and there’s the Justice Department’s national security division,” the official said. “For those things done under court jurisdiction, the courts are intrusive in my business, appropriately so, and there are two congressional committees. It’s a belts-and-suspenders-and-Velcro approach, and inside there’s rich auditing.”
But privacy advocates, such as Sen. Ron Wyden (D-Ore.), said the intelligence committee on which he serves needs “straight answers” to do vigorous oversight.
He added: “The typical person says, ‘If I am law-abiding and the government is out there collecting lots of information about me — who I call, when I call, where I call from’ . . . I think the typical person is going to say, ‘That sure sounds like it could have some effect on my privacy.’ ”
Two of the four collection programs, one each for telephony and the Internet, process trillions of “metadata” records for storage and analysis in systems called MAINWAY and MARINA, respectively. Metadata includes highly revealing information about the times, places, devices and participants in electronic communication, but not its contents. The bulk collection of telephone call records from Verizon Business Services, disclosed this month by the British newspaper the Guardian, is one source of raw intelligence for MAINWAY.
