Indiana State Rep. Phillip Hinkle is being called on to resign amid allegations he proposed sex to an 18-year-old male.

Hinkle's accuser Kameryn Gibson told The Indianapolis Star that the 64-year-old lawmaker exposed himself in a downtown Indianapolis hotel room where the pair had agreed to meet.

Hinkle co-authored the bill that created the state's “In God We Trust” license plate and earlier this year he voted in favor of an amendment that would constitutionally ban the state from recognizing with either marriage or civil unions the relationships of gay and lesbian couples.

Gibson told the paper on Friday that Hinkle responded to his ad looking for a “sugga daddy” and offered him $80 plus a “healthy” tip for “a really good time.” He added that he met the lawmaker, but decided against going further after he learned Hinkle was a state representative.

In one email, Hinkle described himself: “I am an in shape married professional, 5'8”, fit 170 lbs, and love getting and staying naked.”

And in a text message from his Blackberry, he suggested Gibson should spend the night: “If u want to consider spending the nigh u might tell ur sis so she won't worry. Would have u back before 11 tomorrow. No extra cash just free breakfast and maybe late night snack.”

Gibson's sister, Megan Gibson, told the paper that she and her brother were offered $10,000 to keep the matter private.

In an interview with Indianapolis NBC affiliate WTHR, Gibson said Hinkle grabbed his ass.

“When I wanted to leave, he was like … 'cause I said my sister is coming to get me. He was like you're not leaving until we do what we planned to do. And I didn't want to have sex with him,” Gibson said.

“He was just like well you're not going anywhere,” he added. “He grabbed my arm and he grabbed my shirt and then he went sexual with it by touching my butt.”

“And he exposed himself?” the interviewer asked.

“Yes, he did,” Gibson replied. (The video is embedded in the right panel of this page.)

While Governor Mitch Daniels refused to comment on whether Hinkle should resign, calling the matter a “personal family tragedy,” Marion County Republican Chairman Kyle Walker strongly recommended “Hinkle resign his position so that he can focus on his family and not have this situation detract from that or the work that needs to continue in his legislative district.”

Indiana House Speaker Brian Bosma told the Star: “If the circumstances are as reported, it is an extremely sad and disappointing situation for all of us, especially the families involved.”
