In 2004, Without Walls International Church reported a congregation of 20,000, the largest congregation in the area and the seventh-largest church in the United States. An audit later made public by a United States Senate committee chaired by Iowa Republican Chuck Grassley showed that Without Walls received $150 million from 2004 to 2006. The Senate report found the church White-Cain operated with her now ex-husband spent tax-exempt ministry funds one year to pay nearly $900,000 for the couple's waterfront mansion, and over a million dollars in salaries to family members paid for the Whites' private jet. White and her church did not cooperate with the investigation. In 2011, Grassley issued a report outlining his committee's findings but took no additional action.
