WASHINGTON — President Barack Obama declared Friday that America is "going to have to make some choices" balancing privacy and security, launching a vigorous defense of formerly secret programs that sweep up an estimated 3 billion phone calls a day and amass Internet data from U.S. providers in an attempt to thwart terror attacks.
He warned that it will be harder to detect threats against the U.S. now that the two top-secret tools to target terrorists have been so thoroughly publicized.
At turns defensive and defiant, Obama stood by the spy programs revealed this week.
The National Security Agency has been collecting the phone records of hundreds of millions of Americans each day, creating a database through which it can learn whether terror suspects have been in contact with people in the U.S. It also was disclosed this week that the NSA has been gathering all Internet usage — audio, video, photographs, emails and searches — from nine major U.S. Internet providers, including Microsoft and Google, in hopes of detecting suspicious behavior that begins overseas.
"Nobody is listening to your telephone calls," Obama assured the nation after two days of reports that many found unsettling. What the government is doing, he said, is digesting phone numbers and the durations of calls, seeking links that might "identify potential leads with respect to folks who might engage in terrorism." If there's a hit, he said, "if the intelligence community then actually wants to listen to a phone call, they've got to go back to a federal judge, just like they would in a criminal investigation."
While Obama said the aim of the programs is to make America safe, he offered no specifics about how the surveillance programs have done this. House Intelligence Committee Chairman Mike Rogers, R-Mich., on Thursday said the phone records sweeps had thwarted a domestic terror attack, but he also didn't offer specifics.
Obama asserted his administration had tightened the phone records collection program since it started in the George W. Bush administration and is auditing the programs to ensure that measures to protect Americans' privacy are heeded — part of what he called efforts to resist a mindset of "you know, 'Trust me, we're doing the right thing. We know who the bad guys are.'"
But again, he provided no details on how the program was tightened or what the audit is looking at.
The furor this week has divided Congress, and led civil liberties advocates and some constitutional scholars to accuse Obama of crossing a line in the name of rooting out terror threats.
Obama, himself a constitutional lawyer, strove to calm Americans' fears — but also remind them that Congress and the courts had signed off on the surveillance.
"I think the American people understand that there are some trade-offs involved," Obama said when questioned by reporters at a health care event in San Jose, Calif.
"It's important to recognize that you can't have 100 percent security and also then have 100 percent privacy and zero inconvenience," he said. "We're going to have to make some choices as a society. And what I can say is that in evaluating these programs, they make a difference in our capacity to anticipate and prevent possible terrorist activity."
