A lawsuit filed this month against the president and first lady of Oral Roberts University just got a little broader — and a little more salacious.

In the lawsuit, three former professors at Oral Roberts assert that administrators harassed and intimidated them after they accidentally came into possession of a sensitive document drawn up by a university official. The document purported to detail dozens of instances of ethical and financial misconduct by the president of the university, Richard Roberts, and his wife, Lindsay Roberts.

When they sued, the three former professors paraphrased several parts of the document, including allegations that the president had used the university jet to fly his daughter to Florida and the Bahamas on a $30,000 vacation. “Some of the more salacious entries,” the suit said, “have been omitted.”

The Robertses have denied all the allegations, acccusing their accusers of blackmail and extortion.

On Friday, according to the Tulsa World, the three former professors added a copy of the mysterious document itself to their court papers.

The “more salacious entries” include a number of new allegations about Ms. Roberts. According to the Tulsa World, the amended lawsuit says she spent the night in a university guest house “with an underage male nine times, was photographed 29 times in her car with an underage male after midnight and after minors’ curfew, visited Victory Christian School with an underage male 81 times in 2004, smoked with an underage male at her house, and repeatedly moved her ‘male 16-year-old friend’ into her family’s house.”

The amended lawsuit also accuses the university of allowing a known sex offender to work on the campus. The Robertses issued a blanket denial of the fresh allegations, the Tulsa World reported.

Last week on Larry King Live, a television show on CNN, Mr. Roberts said the document had been at least partly written by his sister-in-law, Stephanie Cantees, who was directed in her capacity as a community liaison to keep track of “rumors” circulating about the university.

The three plaintiffs also added a new defendant to their suit. They are now suing the university’s Board of Regents, in addition to the university, its provost, its associate provost, one of its deans, and Mr. Roberts. —John Gravois
