The moves come as gun violence and crime have ticked up in the United States, putting pressure on the White House to take action. Biden was expected to address new steps on guns in a public event Monday afternoon, according to people who have received invitations.
The White House declined to comment on the new steps, which were described by three people familiar with the matter not authorized to speak publicly. Dettelbach did not respond to a request for comment.
The New York Democrat on Sunday blamed Republicans for holding up gun reform legislation, while pressing Biden’s administration to go further. “Today I am calling on the administration to go all after ghost guns, by putting out regulations that will stop them. The federal government has the ability through regulation to stop these ghost guns,” he said.
Following a 2021 directive from the Biden administration, the ATF proposed a rule in May last year to allow the bureau to classify the building blocks that often make up ghost guns as firearms. The rule has been winding its way through the federal regulation process since then.
The ATF rule addresses a key problem in tracking and regulating ghost guns because certain frames and receivers used to assemble the guns are often purchased online and not classified as firearms by the bureau.
The rule would also require manufactures who sell parts to assemble ghost guns to be licensed and to run background checks on potential purchasers of the kits used to assemble the products.
The Justice Department has also launched a national ghost gun enforcement initiative, which will “train a national cadre of prosecutors and disseminate investigation and prosecution tools to help bring cases against those who use ghost guns to commit crimes,” according to the White House.
Ghost guns have been used in multiple recent shootings, including at a Maryland high school in January. The exact number in circulation is unknowable, given the inability of regulators to track them.
Multiple states have moved to restrict their sale as ghost guns become more common at crime scenes.
Last week, Maryland joined Washington, DC, and 10 other states — California, Connecticut, Delaware, Hawaii, Nevada, New Jersey, New York, Rhode Island, Virginia and Washington — in banning or restricting the purchase or use of ghost guns, which are often bought online and assembled at home.
