WASHINGTON, March 5 (Reuters) - ⁠U.S. Senator Elizabeth Warren will introduce legislation on Thursday to stop a ⁠U.S. Army-owned ammunition plant from selling military-grade bullets to civilians, asserting that ‌some are being diverted to armMexican drug cartels and have been used in more than a dozen American mass shootings.

The Stop Militarizing Our Streets Act, co-sponsored by Senator Andy Kim and Representatives Robert ​Garcia and Jamie Raskin, would prohibit Pentagon contractors from ⁠selling military-grade assault weapons and ammunition ⁠to civilians.

It would also require that military contractors only sell firearms and ammunition to ⁠commercial ‌dealers that follow minimum safety practices, such as screening customers and having a low history of gun sales that are later linked to a ⁠crime.

The bill takes aim at the Lake City Army ​Ammunition Plant in Independence, ‌Missouri, a facility built during World War Two to supply the U.S. military ⁠and the ​largest manufacturer of rifle ammunition for the U.S. armed forces.

The facility is run by Olin Winchester, part of Olin Corporation. The Army has a deal with Winchester that whatever ammunition is ⁠not purchased by the service can be sold ​commercially on the civilian market.

High-powered .50-caliber cartridges that Mexican authorities have seized from cartels were traced to the Lake City plant, Warren said.

Neither Olin nor its subsidiary immediately responded to ⁠a request for comment.

"Americans' tax dollars should not be used to fuel gun violence," Warren said in a statement. "Congress must step in to keep Americans safe, and that means stopping the U.S. military and giant defense contractors from selling weapons of ​war to cartels, criminal groups, and mass shooters that terrorize ⁠our communities."

A New York Times investigation in 2023 found that AR-15 ammunition produced at ​the Lake City plant had been used in ‌at least a dozen mass shootings since 2012, ​including the attacks in Aurora, San Bernardino, Las Vegas, Sutherland Springs, Parkland, Buffalo, and Uvalde.
