THE BURNED OVER DISTRICT

Until the prosecutors began to shine a light on how he worked.

Investigators are said to be especially interested in how Tony C. Rudy, a former deputy chief of staff to Representative Tom DeLay of Texas, and Neil G. Volz, a former chief of staff to Representative BobNey of Ohio, obtained lobbying positions with big firms on K Street.

The hiring pattern is "very much a part of" what prosecutors are focusing on, a person involved in the case said. Another participant confirmed that investigators were trying to determine whether aides conducted "job negotiations with Jack Abramoff" while they were in a position to help him on Capitol Hill.

Prosecutors are trying to establish that "it's not just a ticket to a ballgame, it's major jobs" that exchanged hands, the participant in the case said. Also under examination are payments to lobbyists and lawmakers' wives, including Mr. Rudy's wife, Lisa Rudy, whose firm, Liberty Consulting, worked in consultation with Mr. Abramoff, people involved in case said.

This is really much, much more than business as usual, despite what the Republicans wanted or would have you believe.

The Senate hearings uncovered many patterns of Mr. Abramoff's activities, including his offering favors to officials while making deals on government work. In one case, a former senior Interior Department official, J. Steven Griles, testified that Mr. Abramoff had offered him a position at Greenberg Traurig while Mr. Griles was in a position to affect decisions involving Mr. Abramoff's Indian clients. Mr. Griles said he reported the offer to his department's ethics division and rejected it.

Prosecutors are trying to determine whether Mr. Abramoff made similar overtures to other well positioned government workers, especially former aides to Republican leaders in of the House and Senate. Such gestures could be considered as bribery or a conflict of interest, especially if the interests of the two parties were entangled.

Of particular interest, according to several people involved in the case, are how Mr. Rudy, who left Mr. DeLay's office in 2001 to join Greenberg Traurig, and Mr. Volz, who left Mr. Ney's office in 2002 for that firm, obtained their positions. Investigators believe Mr. Abramoff may have solicited help from both men and their supervisors on Capitol Hill while helping arrange for high-paying positions, people familiar with case said.

Mr. Rudy now works for the Alexander Strategy Group, a lobbying firm run by Ed Buckham, another former senior aide to Mr. DeLay. Alexander Strategy is also under scrutiny for its ties to Mr. Abramoff and for putting Mr. DeLay's wife, Christine, on its payroll for several years.

They were running it like it was the family business.
