The National Security Agency’s collection of phone data from all of Verizon’s U.S. customers is just the “tip of the iceberg,” says a former NSA official who estimates the agency has data on as many as 20 trillion phone calls and emails by U.S. citizens.

William Binney, an award-winning mathematician and noted NSA whistleblower, says the collection dates back to when the super-secret agency began domestic surveillance after the Sept. 11 attacks.

“I believe they’ve been collecting data about all domestic calls since October 2001,” said Mr. Binney, who worked at NSA for more than 30 years. “That’s more than a billion calls a day.”

He called his figures “back of the envelope” estimates, adding that they include emails as well as telephone calls.

Mr. Binney, who left the agency in October 2001, said the data were collected under a highly classified NSA program code-named “Stellar Wind,” which was part of the warrantless domestic wiretapping effort — the Terrorist Surveillance Program — launched on orders from President George W. Bush.
