A growing number of Democrats are calling on Senate Majority Leader Mitch McConnell to cancel the chamber’s August recess so that they can take up gun control legislation in the wake of two mass shootings this weekend.

Senate Minority Leader Chuck Schumer, D-N.Y., called on the Republican leader to end the chamber’s break to vote on a universal background check bill after the two shootings — one in Dayton, Ohio, and another in El Paso, Texas — left at least 29 dead and 53 injured in a matter of just 13 hours. The Senate is currently in recess until September.

“One awful event after another. Leader McConnell must call the Senate back for an emergency session to put the House-passed universal background checks legislation on the Senate floor for debate and a vote immediately,” Schumer said in a statement.
