WASHINGTON, Dec. 13 - The ranking Democrat on the Senate committee investigating the Republican lobbyist Jack Abramoff announced on Tuesday that he was returning $67,000 in political contributions from Mr. Abramoff's former partners and Indian tribe clients.
The lawmaker, Senator Byron L. Dorgan of North Dakota, has been accused of hypocrisy by Republicans for having not acknowledged the contributions from Mr. Abramoff's clients while at the same time sharply criticizing him in hearings of the Senate panel, the Indian Affairs Committee.
"Even though those contributions were legal and fully reported as required by law, I will not knowingly keep even one dollar in contributions if there is even a remote possibility that they could have been the result of any action Mr. Abramoff might have taken," Mr. Dorgan said in a statement emphasizing that he had never received a direct contribution from Mr. Abramoff himself.
Mr. Abramoff is now the subject of a federal grand jury investigation in Washington focused on whether his lobbying operation corrupted public officials, including members of Congress, to get them to perform official acts for Indian tribes and their gambling operations. His former lobbying partner Michael Scanlon pleaded guilty last month to conspiracy to bribe public officials.
While Mr. Abramoff and Mr. Scanlon urged their Indian tribe clients to shower most of their political contributions on Republicans, they also urged the tribes to be generous with some Democrats, including Mr. Dorgan and others who might be able to assist on legislation that the tribes sought. Mr. Dorgan has served on the Indian Affairs Committee since 1993.
The senator has been the focus of recent articles by The Associated Press into the timing of a series of contributions from Indian tribes and actions he took that were seen as favorable to them. His decision to return the money was first disclosed in an interview with The Forum, a newspaper in Fargo, N.D., that published an account of it Tuesday.
In his statement, Mr. Dorgan described Mr. Abramoff as a "corrupt individual who bilked Indian tribes out of tens of millions of dollars." He said, "I have never met Jack Abramoff, I have never received a political contribution from him, and I have never knowingly received one that was directed by him." A spokesman for Mr. Abramoff had no immediate response.
A spokesman for Mr. Dorgan, Barry E. Piatt, said the senator had directed his staff to review donations both to his campaign committee and to his political action committee, the Great Plains Leadership Fund, and return any from Mr. Abramoff's former tribal clients or former lobbying partners.
