The New York Police Department says a sergeant has been stripped of her gun and badge and charged internally in the July 2014 chokehold death of Eric Garner.

Sgt. Kizzy Adonis was one of the supervising officers at the scene of Garner's death on Staten Island during an arrest on suspicion of selling loose, untaxed cigarettes. Officials said Friday she was charged with failure to supervise.

Sgt. Ed Mullins is the head of her union and calls the charge ridiculous and political.

Officer Daniel Pantaleo applied the chokehold. He remains on modified duty but has yet to face departmental charges. A federal probe is continuing.

Adonis was recently promoted to sergeant while she was on probation, and under NYPD policy officials had to act on the charges within 18 months.
