Rep. Mike Rogers (R-Mich.), the committee chairman, then stepped forward to say that the number “far exceeds 10.” Rogers defended the collection of data on Americans, saying, “If you’re going to connect the dots on a 9/11-style event . . . you have to have dots in the box in order to connect.”
U.S. officials have so far identified two plots that they say the NSA programs helped to disrupt: a planned suicide bombing on the New York City subway system and a plot to attack a Danish newspaper by a Pakistani American, David C. Headley, who was arrested in 2009 for his role in a deadly attack the year before in Mumbai.
After a separate briefing attended by 47 members of the Senate, Sen. Dianne Feinstein (D-
Calif.) indicated that the NSA is expected to declassify materials on those and other plots early next week. She said the process has been painstaking because Alexander “wants to be exact” with the data presented to the public.
“We’ll make an assessment based” on what Alexander presents, said Feinstein, chairman of the Senate Intelligence Committee. But she also indicated that lawmakers are already planning new legislation that would bar contractors such as Snowden from “handling highly classified technical data.”
The House and Senate hearings were part of a series of appearances on Capitol Hill by senior Obama administration officials to defend and explain the surveillance programs explosed by the leaks.
FBI Director Robert S. Mueller III was asked repeatedly during a House Judiciary Committee hearing to explain how the Foreign Intelligence Surveillance Act, which serves as the basis for the controversial NSA programs, allowed the agency to collect so much data on Americans who are under no legal suspicion.
The law “fails to impose a meaningful limit on the government’s ability to collect this type of information,” said Rep. John Conyers Jr. (D-Mich.). “If every call is relevant, then the relevant standard we enacted into law has little practical meaning.”
Mueller’s response did little to clarify the administration’s position, centering instead on its effectiveness as a rationale. He said the data gathered by the NSA “may be relevant in the future, has been relevant in the past, and its collection in this matter thereby satisfies the requirement for relevance, according to the court.”
Mueller provided little information on the FBI’s pursuit of Snowden, the 29-year-old former CIA employee and NSA contractor, except to say that the bureau is “taking all necessary steps to hold this person responsible for these disclosures.”
Snowden’s whereabouts have been unclear since he checked out of a Hong Kong hotel two days ago, but he has indicated that he will seek asylum and fight extradition to the United States.
Since coming forward Sunday as the source of the NSA leaks, Snowden has alluded to additional U.S. national security secrets that he is prepared to disclose. In an interview in Hong Kong with the South China Morning Post, Snowden said the United States has conducted massive hacking operations against hundreds of Chinese targets since 2009. The newspaper said he had presented “unverified documents” describing those hacking operations.
After scouring Snowden’s employment records and computer access logs, U.S. officials believe he smuggled files from classified networks to which he had access as a systems analyst.
Snowden’s decision to flee to Hong Kong and his disclosures about alleged U.S. cyber operations against the Chinese have raised some suspicions of ties to that government. Rogers said, “We’re going to make sure that there’s a thorough scrub of what his China connections are.”
Other U.S. officials said no evidence has surfaced to substantiate those concerns.
