Swaggart died at the age of 90 in Baton Rouge, LA—two weeks after his son, Donnie, revealed he was in the hospital.

The Pentecostal preacher and pioneer of televangelism had been in critical condition at a Louisiana hospital after suffering a cardiac arrest June 15.

The Rev. Jimmy Swaggart, who built one of the nation's biggest broadcast ministries in the 1980s from his Baton Rouge headquarters, died Tuesday. Swaggart, who went into cardiac arrest on Father’s Day, was 90 years old. Once called "the most charismatic televangelist of the 20th century," by 1986, he was the country’s top-rated TV preacher.
