From his wikipedia article:
In 1986, Swaggart exposed fellow Assemblies of God minister Marvin Gorman, who was having an affair with one of his parishioners. The following year, Swaggart then exposed Jim Bakker's sexual indiscretions and soon after appeared on the Larry King Show stating that Bakker was a "cancer in the body of Christ." As a retaliatory move, Marvin Gorman hired a private-detective to follow Swaggart. During his investigation, the detective found Swaggart in a Jefferson Parish, Louisiana motel on Airline Highway with prostitute Debra Murphree and took pictures as proof of the tryst.[1] Gorman presented Swaggart with the photos in a blackmail attempt trying to force Swaggart to come clean, but Swaggart refused. Gorman then presented the pictures to the presbytery leadership of the Assemblies of God, who decided that Swaggart should be suspended from broadcasting his television program for three months.
On February 21, 1988, without giving the details of his transgressions, Swaggart tearfully spoke to his family, congregation, and audience, saying, "I have sinned against you, my Lord, and I would ask that your precious blood would wash and cleanse every stain until it is in the seas of God's forgiveness."[2] Four days later on a New Orleans morning news show, Murphree stated that while Swaggart was a regular customer, they had never engaged in intercourse.
Against the ruling of the governing body of the Assemblies of God, Swaggart returned to his television pulpit long before his three-month suspension expired. He stated, "If I do not return to the pulpit this weekend, millions of people will go to hell." Believing that Swaggart was not genuinely repentant in not submitting to their authority, the Assemblies of God immediately defrocked Swaggart, removing his credentials and ministerial license.
On October 11, 1991, he was found in the company of another prostitute, Rosemary Garcia.[3] The pair were pulled over by the California Highway Patrol in Indio, California, for driving down the wrong side of the street. According to Garcia, Swaggart stopped to proposition her on the side of the road. When Garcia was asked by the patrolman why she was with Swaggart, she replied, "He asked me for sex. I mean, that's why he stopped me. That's what I do. I'm a prostitute." This time, rather than tearfully confessing to his congregation, Swaggart told his flock that "The Lord told me it's flat none of your business." His son Donnie then announced to the stunned audience that his father would be temporarily stepping down as head of Jimmy Swaggart Ministries for "a time of healing and counseling."
Following the scandals, Swaggart's ministry had been reduced by 85% as of 1995. While his ministry's annual revenue shrunk, his annual salary was still over $350,000 at that time.
Nice to see some good, clean Christian behaviour there.
