Bush used the NSA to spy on US citizens BEFORE 9/11

Bush Authorized Domestic Spying Before 9/11
The evidence referred to (and linked to) int he article pretty much demolishes the administration's arguments that:

• If they had done this before 9/11, they could have prevented the attack.
• Spying on US Citizens is allowed because Congress gave him authorization to threaten to use force. (His "war powers" claim.)

Excerpts:

The National Security Agency advised President Bush in early 2001 that it had been eavesdropping on Americans during the course of its work monitoring suspected terrorists and foreigners believed to have ties to terrorist groups, according to a declassified document.

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 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.
...
According to the online magazine Slate, an unnamed official in the telecom industry said NSA's "efforts to obtain call details go back to early 2001, predating the 9/11 attacks and the president's now celebrated secret executive order. The source reports that the NSA approached U.S. carriers and asked for their cooperation in a 'data-mining' operation, which might eventually cull 'millions' of individual calls and e-mails."
