A half-dozen Democrats who are longtime gun control champions are hoping to keep their fight alive in the GOP-controlled Congress with a new bill that would vastly restrict ammunition capacities.

Sen. Chris Murphy (D-Conn.) on Thursday touted the bill, which would ban magazines of more than 10 rounds, hours after reports circulated that police had foiled a mass shooting plot aimed at Congress.

“Think of the damage that someone could do in the U.S. Capitol with 30 rounds,” he said at a briefing.
The bill is the first piece of gun control legislation since Republican won control of the Senate. Though it has more than 100 co-sponsors in the House, the bill has virtually no chance of a vote in either chamber.

Two years after losing their fight to expand background checks following the mass shooting at a school in Newtown, Conn., the group of lawmakers insisted that their fight was not over.

Rep. Elizabeth Esty (D-Conn), who represents Newtown, said the number of co-sponsors for the bill has doubled in the last year.

“The support is growing,” she said. “The momentum has not stopped.”

Esty joined Sen. Robert Menendez (D-N.J.) as well as Connecticut’s Democratic Senate duo, Murphy and Sen. Richard Blumenthal, to announce the legislation.

Murphy stressed that he has not met “a single hunter or a single person who hunts for sport” who needs more than 10 rounds.

He said those who wanted high-capacity magazines were more interested in “arming against the government.”
