Biden announces pick for ATF and plans to trace "ghost guns"

President Biden on Monday announced Steve Dettelbach as his nominee to lead the Bureau of Alcohol, Tobacco, Firearms and Explosives, as well as new plans to regulate so-called "ghost guns."

Why it matters: With gun violence ravaging communities across America, the Biden administration is looking for administrative solutions to address the proliferation of illegal firearms.

• "This rule will make it harder for criminals and other prohibited persons to obtain untraceable guns," Attorney General Merrick Garland said in a statement.
• Ghost guns, assembled at home from "buy build shoot" kits, have posed a challenge to law enforcement because these guns don't contain serial numbers, making them difficult to track.
• Some 20,000 suspected ghost guns were recovered in criminal investigations last year, according to government data.

Driving the news: Biden announced the new rules during a Rose Garden event on Monday, along with Deputy Attorney General Lisa Monaco.
