COLUMBUS, Ohio (AP) — The fired Ohio State University marching band director says he was working to change its sexualized culture when he was dismissed.

Jonathan Waters detailed the changes he was trying to make in a seven-page document prepared when the university began investigating allegations of problems with the band. His attorney released the document Wednesday night.

The university fired Waters last week after a two-month investigation concluded he knew about but failed to stop rituals that included students being pressured to march in their underwear, sing lewd songs, and perform sexually themed stunts that yielded often-explicit nicknames.

Waters says he was taking steps to change the band's culture of inappropriate behavior and vulgarity.

Also Wednesday, the band's alumni association issued a statement supporting Waters.
