OR gun rights group, sheriff sues to block voter-approved gun control ballot measure

An Oregon gun rights group and a county sheriff have filed a federal lawsuit challenging a voter-approved ballot measure that is one of the strictest gun control laws in the nation.

The Oregon Firearms Federation and Sherman County Sheriff Brad Lohrey filed the lawsuit Friday in U.S. District Court contending the measure scheduled to take effect Dec. 8 is unconstitutional because it violates the Second Amendment right to "keep and bear arms."

The lawsuit seeks to prevent the measure from taking effect.
