The snoopgate situation may predate Shrub's authorization. Per the NYT:

The National Security Agency acted on its own authority, without a formal directive from President Bush, to expand its domestic surveillance operations in the weeks after the Sept. 11 attacks, according to declassified documents released Tuesday.

The N.S.A. operation prompted questions from a leading Democrat, Representative Nancy Pelosi of California, who said in an Oct. 11, 2001, letter to a top intelligence official that she was concerned about the agency's legal authority to expand its domestic operations, the documents showed.

...

Ms. Pelosi, then the ranking Democrat on the House Intelligence Committee, said, "I am concerned whether, and to what extent, the National Security Agency has received specific presidential authorization for the operations you are conducting."

The answer, General Hayden suggested in his response to Ms. Pelosi a week later, was that it had not. "In my briefing," he wrote, "I was attempting to emphasize that I used my authorities to adjust N.S.A.'s collection and reporting."

It is not clear whether General Hayden referred at the briefing to the idea of warrantless eavesdropping. Parts of the letters from Ms. Pelosi and General Hayden concerning other specific aspects of the spy agency's domestic operation were blacked out because they remain classified. But officials familiar with the uncensored letters said they referred to other aspects of the domestic eavesdropping program.
