KNOXVILLE, Tenn. (AP) _ The president of the University of Tennessee's fundraising arm is retiring after less than two years on the job.

The state's flagship public university said in a release Monday that Johnnie Ray, head of the UT Foundation and vice president for deployment and alumni affairs, cited family and other priorities as factors in his decision to leave the school.

The foundation in May fired Bruce Downsbrough, its chief operating officer and executive vice president, after his arrest on federal child pornography charges.

Ray joined the university in November 2011. The effective date of his resignation has not yet been determined.

The school said Lofton Stuart, a vice president of the UT Foundation, will take over while a national search for a permanent replacement is conducted.
