The round of sex scandals has claimed another victim – Wayne Pacelle, the leader of the national Humane Society.

Pacelle resigned Friday, hours after the board of the organization voted to retain his leadership following an extensive debate and investigation.

The HSUS is one of the most prominent animal welfare groups in the nation. Livestock growers often see the group as a bitter political enemy.

Pacelle faced legal claims of sexual misconduct from three employees, including a former employee who said he asked to masturbate in front of her and offered her oral sex in a hotel room in 2006.

Pacelle denied the claims.

He is the second leader of HSUS to resign.

Politico also reported other instances of sexual misconduct by former HSUS vice president Paul Shapiro, who resigned a week earlier.
