WASHINGTON - Private GOP tensions over Tom DeLay's ethics controversy spilled into public Sunday, as a Senate leader called on DeLay to explain his actions and one House Republican demanded the majority leader's resignation. "Tom's conduct is hurting the Republican Party, is hurting this Republican majority and it is hurting any Republican who is up for re-election," Rep. Chris Shays, R-Conn., told The Associated Press in an interview, calling for DeLay to step down as majority leader. DeLay, R-Texas, who was admonished by the House ethics committee three times last year, has been dogged in recent months by new reports about his overseas travel funded by special interests, campaign payments to family members and connections to a lobbyist who is under criminal investigation. A moderate Republican from Connecticut, Shays said efforts by the House GOP members to change ethics rules to protect DeLay only make the party look bad. "My party is going to have to decide whether we are going to continue to make excuses for Tom to the detriment of Republicans seeking election," Shays said. Rick Santorum, the No. 3 Republican in the Senate, said Sunday that DeLay needs to explain his conduct to the public. "Now you may not like some of the things he's done," said Santorum, who is up for re-election next year in Pennsylvania. "That's for the people of his district to decide, whether they want to approve that kind of behavior or not." DeLay, who took center stage in passing legislation designed to keep alive Terri Schiavo, also has found that President Bush and congressional colleagues are distancing themselves from his comments, after her death, about the judges involved in her case.
