“It is unspeakable,” he added. “It really is, to see that kids all over this country who go to a place where they should feel safe where they can focus on learning are now worried about the things we saw in Texas or Florida a few months ago. It’s unspeakable.” Sanders put the blame on the NRA for why legislation has never passed, saying, “the NRA, frankly, which once was believe it or not a gun safety organization, teaching kids how to use guns safely, has moved to become part of, to become, a right-wing political organization far beyond guns, as a matter of fact.” Sanders, an independent senator from Vermont who caucuses with Democrats, has a mixed record on guns, though he has taken a much more firm stance in recent years. Over the course of the 2016 presidential campaign, Democratic rival Hillary Clinton attacked him for being too moderate on the issue throughout his career. He voted multiple times against the Brady Handgun Violence Prevention Act in the early 1990s, which aimed to build a background check system and install waiting periods. But Sanders voted multiple times after the deadly mass shooting in Newtown, Connecticut, to expand background checks for all gun sales and has called for numerous changes to gun laws since then.
