WASHINGTON — The Bush administration built an unprecedented surveillance operation to pull in mountains of information far beyond the warrantless wiretapping previously acknowledged, a team of federal inspectors general reported Friday, questioning the legal basis for the effort but shielding almost all details on grounds that they’re still too secret to reveal.
The report, compiled by five inspectors general, refers to “unprecedented collection activities” by U.S. intelligence agencies under an executive order signed by President George W. Bush after the Sept. 11, 2001, attacks.
Just what those activities involved remains classified, but the inspectors general say that any continued use of the secret programs must be “carefully monitored.”
Most of the intelligence leads generated under what was known as the “President’s Surveillance Program” did not have any connection to terrorism, the report said. But FBI agents told the authors that the “mere possibility of the leads producing useful information made investigating the leads worthwhile.”
The report said that President Bush signed off on both the warrantless wiretapping and other top-secret operations shortly after Sept. 11 in a single presidential authorization. All the programs were periodically reauthorized, but except for the acknowledged wiretapping, they “remain highly classified.”
The report says it is unclear how much valuable intelligence the program has yielded. The report, mandated by Congress last year, was delivered to lawmakers Friday.
