Relating to prohibiting contracts between certain state agencies and the Bureau of Alcohol, Tobacco, Firearms and Explosives.

HB 3591 prohibits Texas state agencies from entering contracts with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). It applies to agencies defined in the bill, including executive branch departments, legislative bodies, and judicial entities. The law takes effect September 1, 2025, and only affects contracts entered after that date - existing contracts remain valid under prior law. This is a procedural restriction on state-federal contracting, not a change to gun regulations.
