October 8, 2015 -- This week, Senate Democrats will reportedly unveil new legislation that would block guns from being sold without background checks. The bill, sponsored by Senators Richard Blumenthal (D-Conn.) and Chris Murphy (D-Conn.), would close a loophole that allows retailers to sell guns without a background check after 72 hours.

Background check legislation last saw a Senate vote in April 2013 after the Sandy Hook Elementary School shooting, when an amendment sponsored by Senator Joe Manchin (D-W.Va.) would have provided a stricter background check process to prevent criminals and those deemed mentally ill from purchasing a gun (you can read the full text of the measure here). The amendment failed to garner the 60 votes required to override a filibuster and was stopped by a vote of 54-46.

  • Senators voting against the 2013 Manchin-Toomey Amendment received, on average, 11 times more money ($25,631) from pro-gun interest groups than senators voting for it ($2,340) between January 1, 2009 and December 31, 2014. In contrast, campaign contributions from anti-gun groups to Senators in the same period were negligible.

  • Six senators received more than $50,000 from pro-gun interest groups between January 1, 2009 and December 31, 2014. Of those, only one (Pat Toomey (R-Pa.), also a co-sponsor of the amendment) supported the stricter background check process.
