The Justice department will open a national "Ghost Gun Initiative" to pursue federal charges against those involved in the trade of such weapons, President Joe Biden has said.
He announced the move on Thursday during an appearance with New York City Mayor Eric Adams.
It comes as Mr Adams calls for help to fight a "pandemic" of gun violence.
Is it possible to get vaxxed against “gun violence”?
Wut?
These guns are self-assembled and sometimes 3D printed, which means they do not contain a serial number and cannot be traced. Background checks are also not required to purchase the assembly kits.
More about controlling than actual crime
The Bureau of Alcohol Tobacco and Firearms (ATF) said that 10,000 were recovered in 2019. Since 2016, about 25,000 privately-made guns have been confiscated nationwide, according to a New York Times report. About 325 were used in homicides, an unnamed senior US official said on Thursday.
Mr Adams, who has frequently compared gun violence to the 11 September 2001 terror attacks, called gun violence "domestic terror that is pervasive in this city and country".
I am sure that attacks on Police and defund the Police movement have nothing to do with the spikes in crime. It’s all due to ‘ghost guns’
