Several gun advocacy groups filed a lawsuit this week challenging new California rules banning the sale of firearms to people under 21, arguing that people ages 18 to 20 years are adults with the legal right to bear arms.
The lawsuit, filed Monday in San Diego, targets multiple California laws, including one introduced last year by Democratic state Sen. Anthony Portantino following the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida.
