July 01, 2014, 4:31 PM — The FBI and CIA can also query the content of U.S. residents' electronic communications that the National Security Agency inadvertently collects when targeting foreign terrorism suspects, an intelligence official said.
While privacy advocates have objected to a so-called "backdoor search loophole" allowing the NSA access to electronic communications by U.S. residents, it was unclear until now whether other agencies also had access to those emails, phone calls and other communications.
The information came out in a letter sent by the U.S. Office of the Director of National Intelligence to Senator Ron Wyden, an Oregon Democrat.
While the CIA and NSA conducted thousands of searches targeting U.S. communications in 2013, the FBI does not track number of searches it does, according to the ODNI's letter. But in any case both the CIA and FBI have access to communications accessed by the NSA, the letter said
The CIA and FBI are allowed to search that information for "foreign intelligence information," and the FBI also to search it to "find and extract evidence of a crime," Deirdre Walsh, ODNI's director of legislative affairs, wrote in the letter.
The letter was sent in response to a question Wyden had asked, during a June 5 hearing, about the number of U.S. searches the NSA was conducting through the Foreign Intelligence Surveillance Act (FISA), a law designed to allow surveillance of foreign suspects.
"The queries in question are lawful, limited in scope, and subject to oversight as approved by the Foreign Intelligence Surveillance Court," Walsh wrote in response. "Contrary to some claims, there is no loophole in the law, nor is the Intelligence Community conducting unlawful or 'backdoor searches' of communications of U.S. persons."
Wyden, a long-time critic of NSA surveillance programs, said searches by the CIA and FBI raise serious questions.
"When the FBI says it conducts a substantial number of searches and it has no idea of what the number is, it shows how flawed this system is and the consequences of inadequate oversight," Wyden said in a statement Monday. "This huge gap in oversight is a problem now, and will only grow as global communications systems become more interconnected."
Walsh's letter, sent to Wyden last week and posted by Wyden's office Monday, said the FBI "does not track how many queries it conducts using U.S. person identifiers."
