Who wrote it?

Guess which crooked politician penned this bit of child erotica:

At age ten the madam put the child in a cage with a bear trained to couple with young girls so the girls would be frigid and not fall in love with their patrons. They fed her through the bars and aroused the bear with a stick when it seemed to lose interest.

I'll reveal my source when someone gets it right.

Update: Well, it's not so fun when everyone just googles it and when it's obvious. (How the hell was I supposed to know that "Scooter Libby" and "child erotica" were synonymous?!) Anyway, my source was Moxie who got it from Shakespeare's Sister.
