Family members of the victims affected by D.C.’s mass shooting in March met with House Majority Leader Steny Hoyer on June 18 to prevent the loosening of gun laws in the District.

According to political leaders, the victims’ relatives are worried about the Second Amendment Enforcement Act—a proposed bill that could make the purchase of weapons easier.

Originally introduced by Representative Travis Childress and Sens. John McCain and Jon Tester, the Second Amendment Enforcement act considerably raises the stakes than earlier gun provisions in the District.

“Whatever our disagreements on guns, there is no justification for Members trying to force their will on the local laws of a jurisdiction where they have not been elected and are not accountable to the voters,” Congresswoman Eleanor Holmes Norton (D-DC), the arranger of the meeting said in a statement.

Norton has met with and written to House and Senate Leaders regarding strategies for defeating the gun bill in the House and Senate.

The March 30 incident claimed the lives of four people and left 10 people injured and occurred just miles away from Capitol Hill.
