I went back and reread some of the transcript. I think the term "sexual assault" is being thrown around rather loosely in this thread. Here's the juicy part, and I've highlighted something that might have escaped notice...
Shortly before meeting Zucker, he says, "I better use some Tic Tacs, just in case I start kissing her. You know I'm automatically attracted to beautiful—I just start kissing them. It's like a magnet. Just kiss. I don't even wait. And when you're a star, they let you do it. You can do anything."
"Whatever you want," Bush says.
"Grab 'em by the pussy, you can do anything," Trump replies, before the two men start talking about Zucker's legs.
The difference between sexual assault and good clean fun is the critical, "they let you do it." Presumably these are adult women in their right minds. We don't need to make willing participation illegal or immoral, do we? I know this country was founded by puritans, but that was a couple hundred years ago. Sex is out of the closet now.
