The honor has been given to State Senator Virg Bernero and not Mayor Tony Benavides.
Bernero calls the endorsement another step in building momentum towards the mayor's seat and says it shows his commitment to public safety.
Mayor Benavides says he's disappointed by the FOP's selection and says it doesn't represent the rank and file of the police. Benavides says the election will come down to two factors, trust and experience.
FOP officials say they conducted interviews with both Benavides and Bernero before making their decision.
