LINCOLN, Neb. (AP) — The Nebraska State Auditor's Office is taking the University of Nebraska to task for some travel expenses that include first-class flights, meal overpayments and expensive oceanfront hotel rooms. A letter from State Auditor Mike Foley sent this week to university officials says his office reviewed 87 documents related to travel expenses for employees at the University of Nebraska-Lincoln and the University of Nebraska Medical Center. State policy limits air travel reimbursement to coach seating, although employees are allowed to upgrade at their own expense. But Foley says UNMC employees bought 20 first-class airline tickets totaling nearly $96,000 paid for by the university.
