From NPR’s fact-check of last night’s vice presidential debate when the topic was gun control:
Kaine was governor of Virginia at the time of the 2007 massacre at Virginia Tech in which 33 people were killed, including the gunman. He has consistently supported expanded background checks, including the Manchin-Toomey bill, which failed to get out of the Senate in 2013. Kaine is a gun owner himself and says he supports the Second Amendment, but he earns an F from the National Rifle Association.
Mike Pence has an A rating from the NRA. He has backed legislation granting immunity to gun manufacturers and supported a bill that would require states with strict gun laws to recognize “concealed carry” permits from states with more relaxed rules.
