A federal judge in Kansas has refused to block a Biden administration rule requiring gun sellers to obtain a license and conduct background checks at gun shows. The ruling impacts Kansas and 19 other states. A coalition of 26 Republican-led states, gun owner groups, and individual gun collectors had filed three federal lawsuits in May against the administration, arguing the new licensing requirements were burdensome. The judge's decision aims to close the 'gun show loophole' by enforcing stricter background checks.
