We all knew this was coming. Hillary Clinton unveiling her new gun control policies, which included the holy grail of liberal proposals–expanding background checks. Yet, she isn’t just going to throw policies out there for progressives to munch on; she’s threatening to use executive action to get some of them enacted (via AP): Her campaign rolled out a robust set of proposals Monday, including using executive action as president to expand background check requirements. Under current federal law, such checks are not required for sales made at gun shows or over the Internet. Clinton pledged to require anyone “attempting to sell a significant number of guns” to be considered a firearms dealer, and therefore need a federal license. She did not say how many gun sales would constitute a “significant” number. Efforts to require such comprehensive background checks have failed several times in recent years in Congress, where Republican leaders have shown no willingness to even hold votes on efforts to curb access to guns. Clinton’s attempt to circumvent staunch opposition would likely spark legal challenges from gun advocates, as well as from Republicans sure to question whether a president has the authority to act directly. Clinton also said she would support a law to expand the definition of domestic abusers barred from buying guns. She also wants to prohibit retailers from selling guns to people with incomplete background checks, as happened in the June case of a man accused of killing nine people at a church in Charleston, South Carolina. Clinton proposed repealing legislation that shields gun manufacturers, distributors and dealers of firearms from most liability suits, including in cases of mass shootings.
