LAS VEGAS — Hours before addressing activists at a national gun safety forum, Joe Biden released an outline that he says will “end our gun violence epidemic.”

The former vice president and top-tier 2020 Democratic White House hopeful’s ideas are familiar from his time as President Barack Obama’s understudy and his 36 years as a senator from Delaware. Biden would, among other things, strip liability protection from gun manufacturers if their products are used in mass shootings. The former vice president also proposes banning “the manufacture and sale of assault weapons and high capacity magazines.”
