Staffer A is Tony Rudy

The Department of Justice's document outlining the charges (pdf) against Jack Aramoff include this:

20. On or about June 6, 2002, defendant ABRAMOFF and a lobbying colleague, who was also a former congressional staffer ("Staffer A") successfully solicited one of Firm B's clients, a distilled beverages company, for a $25,000 payment to CAF. Instead of using the money for CAF and contrary to CAF's tax exempt purpose, defendant ABRAMOFF used this money for his personal and professional benefit to partially pay for a golfing trip to Scotland for public officials, members of his staff and others.

Staffer A is Tony Rudy, DeLay's former chief of staff.

Rudy was registered to lobby for SPI Spirits in 2002 when he was at Greenberg Traurig, Abramoff's former firm. Roll Call previously reported that SPI Spirits gave Capitol Athletic Foundation (CAF) $25,000.

But the kicker: Last November, he New York Times reported about a certain email exchange on November 4, 2005.

"Did you get the message from the guys that Tom wants us to raise some bucks from Capital Athletic Foundation?" Mr. Abramoff asked a colleague in a message on June 6, 2002, referring to the charity. "I have six clients in for $25K. I recommend we hit everyone who cares about Tom's requests. I have another few to hit still."

The e-mail was addressed to Tony Rudy, who had been Mr. DeLay's chief of staff in the House before joining Mr. Abramoff's lobbying firm. Mr. Abramoff said it would be good "if we can do $200K" for Mr. DeLay.
