BATON ROUGE, La. — Televangelist Jimmy Swaggart, who became a household name amassing an enormous following and multimillion-dollar ministry only to be undone by his penchant for prostitutes, has died.

Swaggart died decades after his once vast audience dwindled and his name became a punchline on late night television. His death was announced Tuesday on his public Facebook page. A cause wasn’t immediately given, though at 90 he had been in poor health, having suffered cardiac arrest last month.

The Louisiana native was best known for being a captivating Pentecostal preacher with a massive following before being caught on camera with a prostitute in New Orleans in 1988, one of a string of successful TV preachers brought down in the 1980s and 1990s by sex scandals. He continued preaching for decades, but with a reduced audience.

Swaggart encapsulated his downfall in a tearful 1988 sermon, in which he wept and apologized but made no reference to his connection to a prostitute.

“I have sinned against you,” Swaggart told parishioners nationwide. “I beg you to forgive me.”

He announced his resignation from the Assemblies of God later that year, shortly after the church said it was defrocking him for rejecting punishment it had ordered for “moral failure.” The church had wanted him to undergo a two-year rehabilitation program, including not preaching for a full year.

Swaggart said at the time that he knew dismissal was inevitable but insisted he had no choice but to separate from the church to save his ministry and Bible college.

Swaggart’s downfall came in the late 1980s as other prominent preachers faced similar scandals. Swaggart said publicly that his earnings were hurt in 1987 by the sex scandal surrounding rival televangelist Jim Bakker and a former church secretary at Bakker’s PTL ministry organization.

The following year, Swaggart was photographed at a hotel with Debra Murphree, an admitted prostitute who told reporters that the two did not have sex but that the preacher had paid her to pose nude.

She later repeated the claim — and posed nude — for Penthouse magazine.

The surveillance photos that crippled Swaggart’s career apparently stemmed from his rivalry with preacher Marvin Gorman, who Swaggart had accused of sexual misdeeds. Gorman hired the photographer who captured Swaggart and Murphree on film. Swaggart later paid Gorman $1.8 million to settle a lawsuit over the sexual allegations against Gorman.

More trouble came in 1991, when police in California detained Swaggart with another prostitute. The evangelist was charged with driving on the wrong side of the road and driving an unregistered Jaguar. His companion, Rosemary Garcia, said Swaggart became nervous when he saw the police car and weaved when he tried to stuff pornographic magazines under a car seat.

Swaggart is survived by his wife, Frances, son Donnie, daughter-in-law Debbie, grandson Gabriel, daughter Jill, granddaughter Jennifer, son-in-law Clif, son Matt, daughter-in-law Joanna and nine great-grandchildren.
