The IRS told Oral Roberts University in May 2006 about deficiencies in the way it handled political programs, a university spokesperson said. In a letter, the Internal Revenue Service informed the school they were investigating if ORU improperly participated in political activities, Jeremy Burton, ORU spokesperson said.

Burton says ORU answered questions and complied with changes recommended by the IRS. He would not say what those changes were.

ORU is being sued by three former professors for alleged improper involvement in a Tulsa mayoral race. The suit also claims ORU regents didn't properly oversee the university and its president Richard Roberts. The former professors also say Oral Roberts University allowed a man who previously confessed to "exposing himself to a 15-year-old boy in a school locker room" to mentor college kids.

The professors' attorneys have also released a packet of information they say led to their clients' dismissals. The packet is a list of rumors compiled by Richard Roberts' sister-in-law, his community and government liaison.
