The San Francisco Board of Supervisors unanimously passed a resolution Tuesday declaring the National Rifle Association a domestic terrorist organization and urging other municipalities, states and the federal government to do the same.

The resolution calls out the NRA for inciting acts of violence and spreading "misinformation and propaganda" and encourages the city to assess and limit contracts with vendors affiliated with the NRA. It stops short, though, of putting in place any enforcement mechanisms or new regulations.

"The NRA conspires to limit gun violence research, restrict gun violence data sharing and most importantly aggressively tries to block every piece of sensible gun violence prevention legislation proposed on any level, local state or federal," said Supervisor Catherine Stefani, who sponsored the measure.

A longtime advocate for gun safety, Stefani also introduced a resolution earlier this year that authorized the San Francisco Police Department to use funds from the U.S. Department of Justice to help improve the collection, management and analysis of gun-crime evidence.
