A federal judge in Texas temporarily blocked the Biden administration from enforcing its gun background check rule in the Lone Star State on Sunday evening, one day before the national measure took effect.

U.S. District Judge Matthew Kacsmaryk, an appointee of former President Donald Trump, granted a temporary injunction against the Bureau of Alcohol, Tobacco, Firearms, and Explosives to block the federal rule in Texas, though not in other states that challenged the rule.
