I think this would be a good job for Bill Clinton.

The former presidents recently and noisily raised (a little) money for hurricane victims..."how many former presidents can we pull together for a Lada Gaga photo event?"

Let's get more serious. 

Bill Clinton could take up the cause of "sexual abuse".....he hobnobs with many of these abusive people...he took millions from these abusive people...he parties with these people still...and he had his own abusive way with women, and he has the Clinton Foundation to generate funds and awareness for this good cause. 

He could use his stature..and maybe the money remaining in the Clinton Foundation to improve this problem.

He'd be good and so believeable too, yes?

It'd be a bit mortifying..and humbling for him and for the former first lady, but it'd be a good way to "bring about healing".
