(Salem, OR) -- Majority Democrats in the Oregon House have passed a bill that would impose new restrictions on guns. It would ban so-called ghost guns that don't have serial numbers; it would prohibit 18- to 20-year-olds from buying guns, except those used for hunting; and local governments could prohibit guns in public buildings. Republicans opposed the bill arguing against the ghost gun ban and saying the ban on gun purchases by 18- to 20-year-olds violates the constitution. If the bill becomes law, they say it will end of up in court. The bill now moves to the Senate.
