Support is growing in Congress for a closer look at firearm accessories that make weapons fire more rapidly.
FOX's Jared Halpern has more from Capitol Hill:
A lot of lawmakers here are still learning about bump stocks, an accessory designed to make semi-automatic weapons fire more rapidly:
(Barasso) "For a guy from Wyoming who owns plenty of guns, it's something I'd never heard of until yesterday with this news."
Senator John Barasso is among a growing group of Republicans open to hearings on bump stock legislation. That's encouraging for long-time gun control advocate Democrat Richard Blumenthal:
(Blumenthal) "I think it could be a prelude to other common sense measures gaining traction."
House Republican Carlos Curbelo has introduced a bump stock bill, along with several Senate Democrats.
