Chicago Alderman Jason Ervin (28th) is denying he did anything wrong after a YouTube video surfaced of a bachelor party involving female strippers.
The 2012 video was shot in what appears to be a film screening room.
Ervin says the party was not held in his first floor "aldermanic office or political office ... but on another floor of the building."
He also points out that "no city or campaign funds" were spent for what he describes as a private event for his "family and friends."
Ervin is sitting on a chair on a stage during the video, which ends when a female voice can be heard telling the camera operator to shut it down.
"I am deeply disappointed that an individual, whom I regarded as a friend, would attempt to extort me, my family, and the residents of the Ward for personal gain," Ervin said in a statement.
Attempts to reach Ervin were unsuccessful and his spokesman, Ty Cratic, said the alderman would not be making himself available for comment.
Cratic would not confirm any details of the alderman's extortion allegation or if a police investigation has been launched.
Ervin has been on the City Council since 2011.
