WASHINGTON -- President Barack Obama defended sweeping secret surveillance into U.S. phone records and foreigners' Internet use, declaring them a necessary defence against terrorism, and assuring Americans, "Nobody is listening to your telephone calls."
Taking questions Friday from reporters at a health care event in San Jose, California, Obama said, "It's important to recognize that you can't have 100 per cent security and also then have 100 per cent privacy and zero inconvenience."
It was revealed late Wednesday that the National Security Agency has been collecting the phone records of hundreds of millions of U.S. phone customers. The leaked document first reported by the Guardian newspaper gave the NSA authority to collect from all of Verizon's land and mobile customers, but intelligence experts said the program swept up the records of other phone companies too.
Another secret program revealed Thursday scours the Internet usage of foreign nationals overseas who use any of nine U.S.-based internet providers such as Microsoft and Google.
In his first comments since the programs were publicly revealed this week, Obama said safeguards are in place.
"They help us prevent terrorist attacks," Obama said. He said he has concluded that prevention is worth the "modest encroachments on privacy."
Obama's defence of the two programs came as members of Congress were vowing to change a program they voted to authorize. Civil liberties advocates were crying foul, questioning how Obama, a former constitutional scholar who sought privacy protections as a U.S. senator, could embrace policies with strong echoes of President George W. Bush, whose approach to national security he had vowed to leave behind.
The disclosures have triggered a fierce debate that cuts across party lines and could overshadow a two-day visit by Chinese President Xi Jinping. They come at a particularly inopportune time for Obama, whose administration already faces questions over the federal tax agency's improper targeting of conservative groups and the seizure of journalists' phone records in an investigation into who leaked information to the media.
Obama said he came into office with a "healthy skepticism" of the program and increased some of the "safeguards" on the programs. He said Congress and federal judges have oversight on the program, and a judge would have to approve monitoring of the content of a call and it's not a "program run amok."
"Nobody is listening to your telephone calls," he said. "That's not what this program's about."
He said government officials are "looking at phone numbers and durations of calls."
"They are not looking at people's names and they are not looking at content. But by sifting through this so-called metadata they might identify potential leads of people who might engage in terrorism," Obama said.
The president's remarks followed an unusual late-night statement Thursday from Director of National Intelligence James Clapper, who denounced the leaks of highly classified documents that revealed the programs and warned that America's security will suffer. He called the disclosure of a program that targets foreigners' Internet use "reprehensible," and said the leak of another program that lets the government collect Americans' phone records would change U.S. enemies' behaviour and make it harder to understand their intentions.
Clapper, in his late-night statement, offered new information about both surveillance programs, saying he wanted to correct the "misleading impression" created by out-of-context news articles even as he acknowledged that publicly discussing the programs comes with inherent security risks.
"I believe it is important for the American people to understand the limits of this targeted counterterrorism program and the principles that govern its use," Clapper said.
And so barely 24 hours after the phone records program's existence was first revealed publicly by the Guardian newspaper of Britain, Clapper took the rare step of declassifying and publicly releasing details about the authority used to authorize it, including that it's reviewed by a special court every three months and that the data collected can only be culled when there's reasonable suspicion -- backed by facts -- that the information is connected to a foreign terrorist group.
At issue were two National Security Agency programs that came to light late Wednesday and Thursday after highly classified documents were leaked to the media.
A top-secret court order, first disclosed by the Guardian, requires the communications company Verizon to turn over on an "ongoing, daily basis" the records of all landline and mobile telephone calls of its customers, both within the U.S. and between the U.S. and other countries. Experts said it's likely the program extends to other phone companies as well.
Another secret program came to light when The Washington Post and The Guardian reported that the NSA and FBI can scour America's main Internet companies, extracting audio, video, emails and other documents to help analysts track a person's movements and contacts. Microsoft, Yahoo, Google, Facebook, PalTalk, AOL, Skype, YouTube and Apple were all included. Most denied giving the government direct access.
Clapper alleged that articles about the Internet program "contain numerous inaccuracies." He did not specify what those inaccuracies might be.
The NSA seizure of website and Internet provider records was even more secretive, and began only in the past few years. Clapper said those records, too, are released only with secret court orders, and monitors look only for documents that appear to have come from overseas. The data are not to be used to target U.S. citizens, and the government must try to minimize any information that was mistakenly taken from Americans.
It was not immediately clear how intelligence analysts weed out Americans' online documents from those sent by a citizen of another country. And it's unknown if Internet communications from citizens of the closest U.S. allies -- like Britain, Canada, Australia and New Zealand -- are examined.
Several of the Internet companies, including Apple and Facebook, denied in carefully worded statements that they provided the government direct access to their servers, and said they would not have done so without a court order. But their involvement remained unclear Friday, as the surveillance program was authorized by a court and likely would have set up a designated route to transfer data so that direct access to the servers would have been unnecessary.
In a statement, Facebook founder and CEO Mark Zuckerberg encouraged all governments to be more transparent about programs to keep the public safe.
"It's the only way to protect everyone's civil liberties and create the safe and free society we all want over the long term," Zuckerberg posted on his Facebook page.
Senior administration officials defended the programs as critical tools and said the intelligence they yield is among the most valuable data the U.S. collects. Clapper said the Internet program, known as PRISM, can't be used to intentionally target any Americans or anyone in the U.S. He said a special court, Congress and the executive branch all oversee the program and that data accidentally collected about Americans is kept to a minimum.
Clapper alleged the phone records program, too, has been taken out of context. His defence was echoed hours earlier by leaders of Congress' intelligence panels, who dismissed the furor over what they said was standard three-month renewal to a program that's operated for seven years. Committee leaders also said the program recently helped thwart what would have been a significant domestic terrorist attack.
The NSA must collect the phone data in broad swaths, Clapper said, because collecting it narrowly would make it harder to identify terrorism-related communications. The court prohibits the government from indiscriminately rummaging through the phone data without evidence of a terrorist group connection, he said.
Clapper revealed the government is prohibited from "indiscriminately sifting" through the data acquired. It can only be reviewed "when there is a reasonable suspicion, based on specific facts, that the particular basis for the query is associated with a foreign terrorist organization." He also said only counterterrorism personnel trained in the program may access the records.
But the widespread notion of a government dragnet ensnaring terror suspects and innocent Americans pushed typical political foes to stand together against Obama as he enforces what many likened to Bush-era policies.
"When law-abiding Americans make phone calls, who they call, when they call and where they call from is private information," said Democratic Sen. Ron Wyden. "As a result of the disclosures that came to light today, now we're going to have a real debate in the Congress and the country and that's long overdue."
Officials from Clapper's office, the Justice Department, NSA and FBI briefed 27 senators for some two hours late Thursday at a hurriedly convened session prompted by severe criticism and uncertainty about the program.
"The National Security Agency's seizure and surveillance of virtually all of Verizon's phone customers is an astounding assault on the Constitution," said Republican Sen. Rand Paul. "After revelations that the Internal Revenue Service targeted political dissidents and the Department of Justice seized reporters' phone records, it would appear that this administration has now sunk to a new low."
Paul said he will introduce legislation ensuring that constitutional rights against unreasonable searches and seizures apply to government search of phone records.
The surveillance powers are granted under the Patriot Act, which was passed after the Sept. 11, 2001, attacks and renewed in 2006 and again in 2011. Republicans who usually don't miss a chance to criticize the administration offered full support.
