The wife of televangelist Benny Hinn has filed for divorce in Southern California.

Suzanne Hinn filed papers in Orange County Superior Court on Feb. 1, citing irreconcilable differences.

The couple has been married for more than 30 years.

Hinn operates a church and television studio in Aliso Viejo.

He is one of six televangelists under investigation by Republican Sen. Charles Grassley of Iowa.

Grassley sent letters to six Christian ministries, including Hinn's, in 2007 asking about spending on private planes, oceanside mansions, board oversight and involvement in for-profit businesses.

The ministries have denied wrongdoing.
