The US Supreme Court on Wednesday upheld Biden-era federal regulation of untraceable "ghost guns" -- firearms sold in easy-to-assemble kits -- in a defeat for the powerful gun lobby.
Gun manufacturers and gun rights groups had challenged a 2022 Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) rule that requires ghost guns, like other firearms, to have serial numbers and for their purchasers to undergo background checks.
