Mitch Stein said someone made a complaint to school administrators about Facebook pictures of him surrounded by men in drag. There was also a photo of him with a hot dog.
Stein said there was nothing sexual or inappropriate about the photos. The pictures have been blocked on Facebook.
Stein said he met with the assistant superintendent asking him if it was the way he coached or if it was anything he did.
"He said, 'No, we just hold coaches to a higher standard and you don't meet that standard.' I asked him what is that standard and he wouldn't answer me," Stein said.
Stein's lawsuit asks for damages and that he be reinstated. Stein said he donated his entire coaching salary to the school.
The ousted coach has a new adopted 7-week-old daughter, as well as a 15-year-old daughter. The elder daughter said she supports her father and refuses to transfer.
Superintendent Mike Hendricks said he could not comment on ongoing litigation.
An emotional Stein said he just wants to go back and coach.
Stein has continued to raise money for the school. He has raised $10,000 since being fired.
