Iowa State University is detailing the trips in which a university airplane flew President Steven Leath to and from Minnesota so that he could attend personal medical appointments. Leath announced last month he was reimbursing the university $3,800 for costs of flying to doctors’ visits at the Mayo Clinic in Rochester, Minnesota, a three-hour drive from Ames. The school says the reimbursement covered flights in October 2015 and March 2016.
