PHOENIX (AP) — A southern Arizona lawmaker wants Arizona Attorney General Mark Brnovich to determine if Tucson is breaking state law by destroying guns rather than selling them.

The complaint Republican Rep. Mark Finchem filed Wednesday asks Brnovich to investigate whether Tucson is violating a 2013 law requiring sales of otherwise legal guns.

Finchem says he has proof that Tucson is breaking the law.

City Attorney Mike Rankin says Tucson provided records of sales and destruction of guns to Finchem and will respond to any attorney general inquiry.

Brnovich spokeswoman Mia Garcia says the office hasn’t decided whether to investigate.

Gov. Doug Ducey signed a law this year that says local governments that violate state laws lose their state shared revenue if they don’t stop.

Finchem says Tucson received $172 million last year.
