(CNN) A man testified at an Ohio statehouse hearing Tuesday that Rep. Jim Jordan had called him and asked him to contradict the accounts of his own brother, a whistleblower and alleged victim of sexual abuse by an Ohio State University doctor.

Adam DiSabato's brother Mike said in 2018 that he was sexually abused by OSU doctor Richard Strauss while he was a wrestler there between 1987 and 1991, and that his assistant coach at the time, Jordan, an Ohio Republican, knew about the abuse, which Jordan has denied. Adam DiSabato was also a wrestler at OSU.

"Jim Jordan called me crying, crying. Groveling. On the 4th of July, begging me to go against my brother. Begging me. Crying for a half hour. That's the kind of cover-ups that's going on there," Adam DiSabato testified on Tuesday.

A spokesman for the congressman called Adam DiSabato's claim about the phone calls "another lie."

"Congressman Jordan never saw or heard of any abuse, and if he had he would have dealt with it," Jordan communications director Ian Fury said in a statement to CNN. "Congressman Jordan would never ask anyone to do anything but tell the truth."
