On Monday, the White House announced a series of new measures aimed at decreasing gun violence. In addition to banning ghost gun kits the Biden administration also officially nominated Steve Dettelbach to serve as director of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

Politico reports:

On Monday, the White House said in a statement that Dettelbach “has a proven track record of working with federal, state, and local law enforcement to fight violent crime and combat domestic violent extremism and religious violence — including through partnerships with the ATF to prosecute complex cases and take down violent criminal gangs.”

In addition to Dettelbach’s nomination, the White House announced that the Justice Department has issued a final rule to help stop the spread of so-called “ghost guns” — homemade or makeshift firearms that lack serial numbers.

The final rule “bans the business of manufacturing the most accessible ghost guns” and “clarifies that these kits qualify as ‘firearms’ under the Gun Control Act,” according to the White House. It also will “help turn some ghost guns already in circulation into serialized firearms.”

Furthermore, the White House said the final rule requires firearms dealers “to retain key records until they shut down their business or licensed activity,” and it “ensures that firearms with split receivers are subject to regulations requiring serial numbers and background checks.”

The Biden administration previously nominated David Chipman to serve as ATF director however the nomination was rescinded after Senate Republicans and moderate Democrats refused to support him.
