The Rahm Emanuel campaign is crying foul over some language used to describe him at a Gery Chico endorsement session at the International Union of Operating Engineers Local 150.

During a fiery speech introducing Chico, Jim Sweeney, president of the organization, used what could be construed as an insensitive comparison.

"Rahm Emanuel is nothing but a Wall Street Judas," Sweeney said, suggesting that Emanuel sold out blue collar folks for a big pay day. " ... for a bag of silver that he collected when he went and passed NAFTA."
