“Upon being elected, I will give Congress 100 days to get their act together and have the courage to pass reasonable gun safety laws,” Harris (D-Calif.) said at a town hall meeting sponsored by CNN at St. Anselm College. “And if they fail to do it, I will take executive action.”

An aide with Harris’s campaign said that the scope of her initiative would go beyond what she outlined at the town hall and that she would also close the “boyfriend loophole” to prevent convicted domestic abusers from purchasing guns.

Harris’s comments came during a late-April battle for voter attention as CNN hosted back-to-back town hall events Monday night with five Democratic presidential hopefuls. Harris was preceded by Sens. Amy Klobuchar of Minnesota, Elizabeth Warren of Massachusetts and Bernie Sanders of Vermont, with South Bend, Ind., Mayor Pete Buttigieg following.
