The one-time head of the San Antonio firefighters’ union allegedly threatened to release sensitive personal information about four fire department staffers if they applied for the city’s vacant fire chief position, arrest records show. Christopher A. Steele — who served as union president during the organization’s contentious 2018 contract standoff with the city — was arrested late last week on a third-degree felony charge related to those allegations. He was released on $3,000 bond, according to the Express-News.
