Lawmakers voted 260-160 to amend a bill proposed by DC Delegate Eleanor Holmes Norton regarding the District's gun laws.
The amended bill included a substitute amendment by Rep. Travis W. Childers of Mississippi, expanding the rights of residents to buy and own guns, including semiautomatic weapons.
The amended bill then passed 266-152, with 82 Democrats supporting it and nine Republicans opposing it.
However, the measure is not expected to advance in the Senate..
California Democrat Dianne Feinstein told CQ that she would do everything in her power to block the legislation.
“I’d filibuster it. You bet your life I would,” Feinstein said. “I think it is the height of folly.”
