A bipartisan bill to expand background checks and legislation that would flag mentally unstable gun owners are at the top of possible measures Congress could consider in the wake of the two mass shootings in Dayton, Ohio, and El Paso, Texas.

Minority Leader Chuck Schumer, a Democrat from New York, and Rep. Pete King, a Republican from New York, held a joint press conference in Long Island calling on Senate Majority Leader Mitch McConnell to convene the Senate in August and call up a vote on legislation that would require a background check for every gun purchase, including now-excluded gun shows and private sales.
