See NPR: Calif. Lawmaker Quits Over Taped Sex Comments
In a recording of a legislative hearing, Duvall can be heard talking about a recent sexual escapade with a woman he says is 18 years younger.
"I'm getting into spanking her," Duvall is heard to say on the videotape.
The other man asks if she likes it, too. Duvall responds: "She goes, 'I know you like spanking me.' I said, 'Yeah, that's 'cause you're such a bad girl."'
...Duvall received a 100 percent rating from Capitol Resource Institute, a conservative advocacy group, for his votes on legislation considered pro-family during the 2007-08 legislative session.
