WASHINGTON — Thousands of pages of internal e-mail and once-secret Congressional testimony showed Tuesday that Karl Rove and other senior aides in the Bush White House played an earlier and more active role than was previously known in the 2006 firings of a number of United States attorneys.


Aides to former President George W. Bush have asserted that the Justice Department took the lead in the dismissals, which set off a political firestorm that lasted months. Mr. Rove played down his role in the firings in a recent interview and in closed testimony last month before Congressional investigators.

But the documents, released by the House Judiciary Committee after a protracted fight over access to White House records and testimony, offer a detailed portrait of a nearly two-year effort, from early 2005 to 2007, by senior White House officials, including Mr. Rove, to dismiss some prosecutors for what appear to be political reasons.

Internal e-mail messages in the spring of 2005 at the White House showed that there was widespread unhappiness with David Iglesias, the United States attorney in New Mexico, because of the perception among top Republicans that he was dragging his feet on voter fraud and corruption investigations involving Democrats.

In a June 2005 message, Scott Jennings, a top political aide to Mr. Rove, wrote a colleague that Mr. Iglesias should be removed because Republicans in New Mexico "are really angry over his lack of action on voter fraud stuff."

"Iglesias has done nothing," it continued. "We are getting killed out there."

Mr. Iglesias was ultimately let go in December 2006, along with seven other federal prosecutors in an unusual dismissal of top presidential appointees. Mr. Iglesias had received positive evaluations from the Justice Department in Washington for his performance and his "exemplary leadership." It is unclear who made the final decision to have him dismissed.

"The amount of backstabbing and treachery involved is just breathtaking," Mr. Iglesias said of the White House e-mail, in an interview on Tuesday. "It's astounding that without reviewing the evidence or talking to the F.B.I. or anything, the White House would assume that these were provable cases and that I needed to file them for the political benefit of the party. That's not what U.S. attorneys do." ...
