The NSA's vast data-mining activities began shortly after Bush was sworn in as president and the document contradicts his assertion that the 9/11 attacks prompted him to take the unprecedented step of signing a secret executive order authorizing the NSA to monitor a select number of American citizens thought to have ties to terrorist groups.
In its "Transition 2001" report, the NSA said that the ever-changing world of global communication means that "American communication and targeted adversary communication will coexist."
"Make no mistake, NSA can and will perform its missions consistent with the Fourth Amendment and all applicable laws," the document says.
What had long been understood to be protocol in the event that the NSA spied on average Americans was that the agency would black out the identities of those individuals or immediately destroy the information.
But according to people who worked at the NSA as encryption specialists during this time, that's not what happened. On orders from Defense Department officials and President Bush, the agency kept a running list of the names of Americans in its system and made it readily available to a number of senior officials in the Bush administration, these sources said, which in essence meant the NSA was conducting a covert domestic surveillance operation in violation of the law.
"The president personally and directly authorized new operations, like the NSA's domestic surveillance program, that almost certainly would never have been approved under normal circumstances and that raised serious legal or political questions," Risen wrote in the book. "Because of the fevered climate created throughout the government by the president and his senior advisers, Bush sent signals of what he wanted done, without explicit presidential orders" and "the most ambitious got the message."
The NSA's domestic surveillance activities that began in early 2001 reached a boiling point shortly after 9/11, when senior administration officials and top intelligence officials asked the NSA to share that data with other intelligence officials who worked for the FBI and the CIA to hunt down terrorists that might be in the United States. However the NSA, on advice from its lawyers, destroyed the records, fearing the agency could be subjected to lawsuits by American citizens identified in the agency's raw intelligence reports.
The declassified report says that the "Director of the National Security Agency is obligated by law to keep Congress fully and currently formed of intelligence activities." But that didn't happen. When news of the NSA's clandestine domestic spying operation, which President Bush said he had authorized in 2002, was uncovered last month by the New York Times, Democratic and Republican members of Congress appeared outraged, claiming that they were never informed of the covert surveillance operation. It's unclear whether the executive order signed by Bush removes the NSA Director from his duty to brief members of Congress about the agency's intelligence gathering programs.
Eavesdropping on Americans required intelligence officials to obtain a surveillance warrant from a special court and show probable cause that the person they wanted to monitor was communicating with suspected terrorists overseas. But Bush said that the process for obtaining such warrants under the 1978 Federal Intelligence Surveillance Act was, at times, "cumbersome."
In a December 22, letter to the Senate Select Committee on Intelligence, Assistant Attorney General William E. Moschella wrote that the "President determined it was necessary following September 11 to create an early warning detection system. FISA could not have provided the speed and agility required for the early warning detection system."
More than a dozen legal scholars dispute Moschella's legal analysis, saying in a letter just sent to Congress that the White House failed to identify "any plausible legal authority for such surveillance."
"The program appears on its face to violate existing law," wrote the scholars of constitutional law, some of whom worked in various senior capacities in Republican and Democratic administrations, in an extraordinary letter to Congress that laid out, point by point, why the president is unauthorized to permit the NSA to spy on Americans and how he broke the law by approving it.
