Used official letterhead to solicit donations for the Charles B. Rangel Center for Public Service at the City College of New York, which is prohibited by congressional rules.
Maintained four rent-stabilized apartments in a Harlem apartment complex, one of which was used as his campaign office, despite city and state regulations that say such units are only to be used as primary residences.
Failed to disclose taxable income on a guest house he owns at the Punta Cana Yacht Club in the Dominican Republic.
Stored his old Mercedes-Benz for free in a House of Representatives parking garage for years, another violation of congressional rules.
In July, Rangel formally asked the ethics committee to investigate his use of congressional letterhead saying, "none of these letters made any reference to or in any way solicited financial contributions to the Center." He has said that he did not violate any ethics rules and that he would give up the rent-controlled apartment that he used as a campaign office. In regards to his apartment in the Dominican Republic, Rangel blamed "cultural and language barriers" for his failure to report $75,000 in rental income. When the New York Post confronted Rangel with the parking allegations, he said, "I told you I am not discussing that. I want to be kind and gentle -- please let me be."
Rep. William "Cold Cash" Jefferson (D-La.)
He may be facing a 16-count indictment, but Rep. Jefferson won a primary run-off election against Democratic challenger Helena Moreno. He is heavily favored to win the December general election, which was delayed due to Hurricane Gustav.
Jefferson was indicted last year as part of a corruption probe on 16 charges, including racketeering, solicitation of bribes, money laundering and obstruction of justice. Jefferson pleaded not guilty and is expected to go to trial late this year. If convicted on all charges, he could face 235 years in prison.
In court papers, FBI agents say Jefferson was videotaped accepting marked money supposedly to pay a bribe to a Nigerian official. The FBI says $90,000 in marked money was found in Jefferson's freezer during a raid.
Jefferson represents New Orleans and in 2005 ABC News reported that amid the chaos after Hurricane Katrina struck, Jefferson used National Guard troops to check on his property and rescue his personal belongings -- even while New Orleans residents were trying to get rescued from rooftops.
Rep. Tom Feeney (R-FL)
Rep. Feeney will not serve a 4th term in Congress after losing his seat to Democrat Suzanne Kosmas. With almost all precincts in his Florida district reporting, Feeney only managed to capture 41 percent of the vote, compared with Kosmas' 57 percent.
His constituents were apparently unwilling to forgive the "rookie mistake" that Feeney admitted to making when he made a trip overseas in 2003 that was paid for convicted lobbyist Jack Abramoff. The two other politicians trip on the trip, Bob Ney of Ohio and former House Majority Leader Tom Delay, have faced troubles of their own because of connections to Abramoff. Ney pled guilty to federal charges and served 17 months in prison, while Delay has been indicted in Texas on unrelated charges for allegedly violating election fundraising laws.
