FILE – This May 19, 2018 file photo released by the National Park Service shows Grand Canyon National
Park Superintendent, Christine Lehnertz at Grand Canyon National Park, Ariz. Lehnertz has not returned
to her job nearly a month after being cleared of accusations she created a hostile work environment,
improperly disciplined an employee and wasted park resources. The park announced last month that the
investigation by the Interior Department’s Office of Inspector General fully exonerated Lehnertz. The
allegations were made public Tuesday, March 5, 2019, when the office released its investigative report.
