Good lord, people! I've read the entire thread now, and those of you defending Franken's harassment or comparing it to Moore's serial dating high school girls, and being accused of attempted rape... I wanna Gibbs-smack the back of all your heads.
A forced kiss can be considered an assault, except the woman said she eventually consented to "rehearsing" the kiss because he was harassing her. Then he went too far with it, and she forcefully rejected him, warning him never to try that again. His ego was clearly bruised, so when she was asleep and vulnerable, he set about to humiliate her with that damned photo as a "joke".
Joke-smoke, he was angry at the rejection (and doesn't remember the kiss the same way because it was probably the highlight of his trip) and he got back at her in a childish, pathetic manner.
Nobody should be approving the behavior or minimizing it, nor should anyone be comparing it to sexual assault or rape. Get a grip, folks... and you know who you are.
