Voices from Newtown. A new Clinton campaign television ad stars Erica Smegielski, the daughter of the school principal who was killed in the Sandy Hook shooting. Smegielski’s mother, Dawn Hochsprung, was one of 26 victims. In the ad Smegielski says, “No one is fighting harder to reform our gun laws than Hillary.” Clinton’s proposed reforms include ending legal immunity for gun-makers whose merchandise is used in violent crimes.
