WASHINGTON (AP) -- For years, top officials of the Bush and Obama administrations dismissed fears about secret government data-mining by reassuring Congress that there were no secret nets trawling for Americans' phone and Internet records.
"We do not vacuum up the contents of communications under the president's program and then use some sort of magic after the intercept to determine which of those we want to listen to, deal with or report on," then-CIA Director Michael Hayden told a Senate Judiciary Committee hearing in July 2006.
But on Friday, President Barack Obama himself acknowledged the existence of such programs even as he gave the government's standard rationale to ease fears that Americans' privacy rights are being violated.
"By sifting through this so-called metadata, they might identify potential leads of people who might engage in terrorism," Obama said during an exchange with reporters at a health care event in San Jose, Calif.
Obama's comments marked the first time a U.S. president publicly acknowledged the government's electronic sleuthing on its citizens. They came in response to media reports and published classified documents that detailed the government's secret mass collection of phone and Internet communications.
When top officials in the Obama and Bush administrations have been asked in recent years whether U.S. citizens' communications were swept up as part of government surveillance, they've often responded with swift, flat denials. The denials were often carefully constructed to avoid any hints of the activities they were denying.
Even Obama's predecessor, George W. Bush, sidestepped what he described as a kerfuffle about his administration's secret electronic intelligence-gathering.
During a March 2006 appearance at the City Club of Cleveland, Bush described the NSA effort only as "a program that will enable us to listen from a known al-Qaida person and/or affiliate from making a phone call outside the United States in or inside the United States out, with the idea of being able to pick up quickly information for which to be able to respond in the environment we're in." He added: "I believe what I'm doing is constitutional, and I know it's necessary. And so we're going to keep doing it."
His vice president, Dick Cheney, was more blunt during a radio appearance, denying the government was engaging in domestic surveillance.
"This is not a domestic surveillance program," Cheney told radio host Hugh Hewitt, adding that "what we're interested in are intercepting communications, one end of which are outside the United States and one end of which we have reason to believe is al-Qaida-related."
Technically, Cheney's description of the program was accurate. His insistence that the Bush administration was not engaged in domestic surveillance is more debatable.
Reports that first appeared in Britain's Guardian newspaper and The Washington Post indicate that the NSA pulls in phone records, though not the actual content of the calls, from its secret warrants allowing it to collect data from major telecom companies. The program is aimed at detecting the calling patterns of terrorist suspects. A separate government program also collects massive amounts of data from at least nine Internet and electronic firms, pulling in everything from emails to photographs. Obama said Friday that the electronic data-mining is not aimed at American citizens or inside the U.S.
Several top Bush administration officials adamantly insisted that the government was not engaged in mass data-trawling as part of its secret NSA programs.
After a New York Times expose raised concerns about NSA targeting Americans' phone records, Hayden told a National Press Club audience in January 2006 that there was no effort to cast a wide net over communications data.
"This is targeted and focused," said Hayden, the principal deputy director of national intelligence at the time. "This is not about intercepting conversations between people in the United States. This is hot pursuit of communications entering or leaving America involving someone we believe is associated with al-Qaida."
Bush's attorney general, Alberto Gonzales, also minimized the reach of the NSA data-gathering, telling a Senate Judiciary hearing in February 2006 that "this surveillance is narrowly focused and fully consistent with the traditional forms of enemy surveillance found to be necessary in all previous armed conflicts."
Bush administration officials were repeatedly pressed by Congress about the NSA efforts in 2005 and 2006, as the Senate and House debated whether to extend the Patriot Act and many of its provisions that gave the government broad power to conduct surveillance and data collection. But once the Patriot Act's main provisions were reauthorized and signed into law by Bush in March 2006, public congressional concerns over the NSA's authority seemed to dissipate.
