The Biden administration has announced a significant expansion of gun background checks, aimed at closing the 'gun show loophole.' This move, described as the largest expansion in decades, requires more gun dealers to obtain federal licenses and conduct background checks, regardless of where they sell guns, including online, at gun shows, and in other informal settings. The rule, set to go into effect soon, mandates that gun dealers obtain federal licenses and conduct checks, in alignment with the goals of the Bipartisan Safer Communities Act. It is expected to affect nearly 25,000 currently unlicensed dealers. While the rule has been praised for its potential to save lives by keeping guns out of dangerous hands, it has also drawn criticism and is expected to face GOP backlash and legal challenges.
