Portland mayor tells student rally he'll seek city-wide 'assault weapon' ban

Portland mayor tells student rally he'll seek city-wide 'assault weapon' ban: Though Wheeler may want city leaders to act tough on guns, state firearm preemption laws forbid local governments from regulating the “sale, acquisition, transfer, ownership, possession, storage, transportation or use” of guns in any way. But the former Oregon State Treasurer and political ally of Gov. Kate Brown said he is going to work on that as well. “I am going to Salem during this next legislative session and I’m going to ask the Governor and the legislature to lift the preemption in Oregon,” Wheeler said.
