Schottel wants a preliminary injunction to block the show from holding contestant interviews scheduled Friday in St. Louis until his case is heard.
Beyond that, he wants an order that he "and others similarly situated" be considered for the program, the report said.
"I'm a fan of the show, and I'm a fan of Mr. Trump, and I don't think he would support any kind of discrimination," said Schottel.
A Trump spokeswoman referred questions to Mark Burnett Productions LLC, a Los Angeles company that produces the show and is a co-defendant in the suit. A Mark Burnett spokesman did not return calls, the newspaper said.
