The President of A-T Still University in Kirksville has gone on medical leave after his second drunk driving arrest in three years. The school is not saying if the leave given James McGovern is linked to the arrest. The former president of Truman State University, Jack Magruder, will become acting president while McGovern is gone. Magruder had to resign from the Still University board to take the appointment. A-T Still University offers degrees in osteopathic medicine.
