Efforts to secure a congressional vote for the District derailed on Tuesday, fewer than 48 hours before D.C. Del. Eleanor Holmes Norton planned to bring the voting rights bill to the House floor.

House Majority Leader Steny Hoyer said provisions to the bill stripping D.C. of most of its gun control laws crippled the measure this week, days after the Maryland congressman said lawmakers were gearing up to approve a pared-down version of the gun amendment.
