Lawmakers, lobbyists, Bush administration officials, congressional staffers and others caught up in the Jack Abramoff public corruption probe:
_Abramoff, a prominent Republican lobbyist, was sentenced in September 2008 to four years in prison on charges of mail fraud, conspiracy and tax evasion. The once-powerful lobbyist cooperated with the federal investigation of influence-peddling in Washington. He was sentenced to a six-year prison sentence in a criminal case in Florida, where he pleaded guilty in January 2006 to charges of conspiracy, honest services fraud and tax evasion in the purchase of gambling cruise boats. He was released to a halfway house in June 2010, then home confinement and has written a book to be published next month.
_David Safavian, the former chief procurement officer in President George W. Bush's administration, was sentenced in October 2009 to a year in prison after being found guilty on four counts in a retrial in December 2008. His 2006 conviction on similar charges was overturned on appeal. The U.S. Circuit Court of Appeals upheld his second conviction for lying to investigators about his relationship with Abramoff, who provided gifts in return for information from Safavian about government property the lobbyist wanted to acquire.
_Kevin Ring, an ex-lobbyist who worked for Abramoff, was convicted in November 2010 of bribing public officials with expensive meals and exclusive event tickets. An earlier jury could not agree on a verdict on charges that Ring showered tickets and meals on employees of then-Republican Reps. John Doolittle of California and Ernest Istook of Oklahoma and the Justice Department in return for congressional appropriations and other assistance for Abramoff's clients. The second trial found him guilty of conspiracy, honest services fraud and giving an illegal gratuity. He was sentenced to 20 months in prison but doesn't have to serve time until an appeal of his conviction has been decided.
_Former Rep. Bob Ney, R-Ohio, was sentenced to 2 1/2 years in prison and was released early in August 2008. He acknowledged taking bribes from Abramoff. Ney was in the traveling party on an Abramoff-sponsored golfing trip to Scotland that was at the heart of the case against Safavian.
_Former Deputy Interior Secretary Steven Griles, the highest-ranking Bush administration official convicted in the scandal, was sentenced to 10 months in prison for obstructing justice.

_John Albaugh, former chief of staff to Istook, pleaded guilty to conspiracy to defraud the House. Albaugh admitted that he accepted meals and sports and concert tickets, along with other perks, from lobbyists in exchange for official favors.

_William Heaton, Ney's former chief of staff, pleaded guilty to a federal conspiracy charge involving a golf trip to Scotland, expensive meals, and tickets to sporting events between 2002 and 2004 as payoffs for helping Abramoff's clients.

_Neil Volz, a former chief of staff to Ney who left government to work for Abramoff, was sentenced to two years' probation, 100 hours of community service and a $2,000 fine after pleading guilty to conspiring to corrupt Ney and others with trips and other aid.
_Mark Zachares, former aide to Rep. Don Young, R-Alaska, pleaded guilty to conspiracy.

He was sentenced to four years' probation and 12 weekends in jail.
_Trevor L. Blackann, a former aide to Missouri Republicans Sen. Kit Bond and Rep. Roy Blunt, pleaded guilty to not reporting $4,100 in gifts from lobbyists in return for helping clients of Abramoff and his associates.

_James Hirni, a former Republican Senate aide and one-time Abramoff associate, pleaded guilty to using wire communications to defraud taxpayers of congressional aides' honest services.
