FBI Director Kash Patel was removed as the Acting Director of the Bureau of Alcohol, Tobacco, Firearms and Explosives and replaced by U.S. Army Secretary Daniel Driscoll, seven people familiar with the matter said on Wednesday.

Driscoll will continue to serve as Army Secretary while he also oversees the ATF, an arm of the U.S. Justice Department, said three of the sources, who were granted anonymity to discuss personnel matters that were not yet public.

An Austin gun shop owner succeeded Friday on a years-long quest to overturn a federal ban on bump stocks, winning a 6-3 victory from the U.S. Supreme Court.

Bump stocks are devices that allow semi-automatic rifles to fire hundreds of rounds in a minute. The court ruled the federal Bureau of Alcohol, Tobacco, Firearms and Explosives can not include bump stocks under legislation banning machine guns. The overturned ATF rule required owners of bump stocks to either destroy them or surrender them to the ATF to avoid criminal prosecution.

The U.S. Supreme Court on Thursday ruled that a bump stock does not transform a firearm into an automatic weapon, striking down a federal rule that banned bump stocks. 

In a 6-3 decision, Justice Clarence Thomas wrote, "Congress has long restricted access to "'machinegun[s],'" a category of firearms defined by the ability to "shoot, automatically more than one shot . . . by a single function of the trigger." 

The Supreme Court on Friday overturned a Trump-era ban on bump stocks, ruling that the Bureau of Alcohol, Tobacco, Firearms and Explosives exceeded its authority by determining that the gun attachments turn firearms into machine guns.

The case was decided 6-3, with Justice Clarence Thomas writing the majority opinion and Justice Samuel Alito concurring. Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson, the courts three liberals, dissented.

Republican backers of a once-in-a-generation gun violence bill now lead the charge against one part of the Biden administration’s implementation of the law, a falling out that illustrates the delicacy of trust required to pass legislation on hot-button issues.

A Congressional Review Act joint resolution of disapproval introduced Wednesday in the Senate by John Cornyn, R-Texas, could force the chamber to vote on overturning a rule from the Bureau of Alcohol, Tobacco, Firearms and Explosives that would expand the number of gun sellers who would be required to run background checks.

The U.S. Supreme Court has sided with the Biden administration, temporarily allowing enforcement of regulations over so-called "ghost guns" that can be made from kits at home.

The administration appealed a federal judge’s earlier ruling tossing out the regulations. In a 5-4 vote, the high court put that ruling from Texas on hold while the case is appealed further on the merits. The regulation will be enforced while the case is appealed to the 5th U.S. Circuit Court of Appeals in New Orleans and possibly further to the Supreme Court. 

The Supreme Court on Tuesday allowed the Biden administration to temporarily reinstate a rule by the Bureau of Alcohol, Tobacco, Firearms, and Explosives regulating “ghost guns” while a challenge to the rule continues in a federal appeals court. In June, a federal judge in Fort Worth, Texas, had barred the ATF from enforcing the rule anywhere in the United States. Urging the justices to intervene, U.S. Solicitor General Elizabeth Prelogar had told the justices that the order by U.S.
