When he worked on Clinton's case he wanted to ask very detailed, embarrassing questions, for the hell of it.
Yet today he's entirely changed his opinion & doesn't think presidents should be bothered with being questioned, until they are out of office.
This, IMO, is the lure for Trump.
Being awkward & going for 'it', covering her mouth so she couldn't call for help is an entirely different scenario, its criminal.
And like you said, he danced during his hearing, he was too cute & its going to cost him. His reputation is forever tainted.
