Sexual assault accusations against veteran comedian Bill Cosby have become an issue in a political campaign. The AP reports that Cosby is being brought up in attack ads in a race for a prosecutor’s post in Pennsylvania.

“Democrat Kevin Steele hopes to become the top prosecutor in Montgomery County, outside Philadelphia. His opponent is Republican Bruce Castor, the former prosecutor who is trying to win back his old job,” the AP reports. “Steele’s new ad attacks Castor for not charging Cosby in 2005 when a woman said the comedian had drugged and molested her.”

More than 50 women have now come forward with similar allegations against Cosby.

Steele is the top assistant to the new prosecutor in the county, who has reportedly reopened an inquiry into the Cosby case. The AP says Cosby settled a civil lawsuit with his accuser in the case.

Castor responded to the new ad by saying he didn’t have sufficient evidence to bring charges against Cosby back in 2005. The AP quotes Castor saying the ad is the work of a “desperate candidate.”
