The woman called the incident a "nightmare" but said didn't she report it because she didn't want to embarrass herself, her family or the Republican Party, according to a police report. She changed her mind after seeing the latest allegations, the report said.

Kramer acknowledged kissing her good night but denied groping her. Asked if the woman ever told him to stop, he told detectives, "I am sure she said something about it not going any further. That is why I went home. I am sure that happened, but I don't remember it. I have been turned down a lot."

Kramer told detectives he had been friends with the woman and that she had made a pass at him in 2008. That alleged event could end up playing a prominent role in the case.

"The defense certainly is going to scrutinize the claims and conduct of the witnesses," Borda said.

While Kramer's political career is almost surely over, how it reaches its formal end remains unclear. He has already said he won't seek re-election in November but has refused to step down before then.

The Assembly has adjourned for the year, but Democrats have demanded that he resign from his job, which pays $50,000 a year. Republicans have also called on him to resign but say they won't push to expel him from office.
