One month after the 2016 Orlando nightclub shooting, Blunt voted for two Republican-sponsored bills. The first was proposed by John Cornyn and would have enabled a 72-hour waiting period for federal authorities to investigate individuals seeking to buy guns who are listed on the terrorist watch list. The second bill, proposed by Chuck Grassley, would have expanded background checks and made it illegal for individuals with certain mental health disorders to purchase guns. Neither bill passed. Blunt voted against two Democrat-sponsored bills, both which also did not pass, including one that would have made background checks required for online gun sales and gun sales at gun shows and another that would have not allowed anyone on the terrorist watchlist to purchase a gun.
