Like the Jim and Tammy Bakker story, the Jimmy Swaggart scandal promises to continue for a long time, with more bits and pieces coming in. The fallen TV evangelist, who stepped down from his electronic pulpit last week after his tearful admissions of unspecified sins, made a brief appearance before his congregation yesterday to thank members of all religions for their support during the "darkest week" he has experienced. His unspecified sins reportedly are that he visited a prostitute and tried to make a deal with a minister who confronted him about it.

About 4,000 worshipers were at the Jimmy Swaggart World Ministries Center in Baton Rouge, La., yesterday when he thanked them in a brief, subdued address. "Not only Pentecostal, but Baptists, Methodists, Presbyterians, Lutherans and Catholic ... even my Moslem friends, I'm serious, have called and said 'we love you, we pray for you,' " said Swaggart. And Swaggart has received a call of support from former television preacher and current presidential candidate Pat Robertson. Swaggart vowed that after a few months away from his pulpit he will continue his worldwide ministry.

James Watt revisited, briefly: The former Interior secretary said in Utah last week that Cuba's purported use of isolation camps for AIDS victims is a good idea, but added that the United States wouldn't have the courage to adopt the policy. As to his statement about the ethnic makeup of an advisory panel that led to his resignation -- "a black ... a woman, two Jews and a cripple" -- Watt said the only offensive word he used was "cripple." He told students at Weber State College that "the new word is 'handicapable.' I'm from Wyoming and didn't know that" ...
