A gun control advocacy group that poured $216,500 into New Mexico’s 2016 legislative elections is finding at least one of its beneficiaries is a tough sell on expanding background checks for gun sales. Everytown for Gun Safety donated $5,000 to then House Majority Leader Nate Gentry, R-Albuquerque, last June. The group also sent a mailer supporting Gentry, who is now the minority leader after Democrats regained control of the House. But late Friday, Gentry joined other Republicans on the House Judiciary Committee in voting against House Bill 50, which would require background checks at gun shows or online, including gun sales by private individuals. After extensive debate in two committees, the measure next goes to the House floor.
