Shannon Watts founded Moms Demand Action for Gun Sense in America after the tragic mass shooting at Sandy Hook in December of 2012. She recognized that moms were looking for a way to organize as a group to stand up for sensible gun laws. The organization’s influence has since spread across the country, becoming the voice of thousands of moms, dads, grandparents and gun sense advocates. Moms Demand Action supports the 2nd Amendment, but believes in common-sense solutions can help decrease the escalating epidemic of gun violence that kills too many of our children and loved ones every day. With this mission, the organization has achieved unprecedented victories against the gun lobby, at the ballot box, in state legislation, and in corporate America. Watts has inspired a grassroots following of millions of passionate gun sense advocates. See an interview with Watts here.
