This bill would amend federal law to allow states to install temporary protective fencing, including razor wire and barbed wire, within 25 miles of the U.S.-Mexico border to deter illegal immigration. The legislation prevents federal employees from removing or tampering with any such fencing that a state has erected, unless the federal government can prove by clear and convincing evidence that the fencing was actually intended to facilitate rather than prevent unlawful immigration. The Attorney General could seek court orders to force states to remove fencing only if that high legal standard is met. The bill affects border states, particularly Texas and other states along the southwest border, by giving them authority to deploy these barriers without federal interference. The legislation contains no specific funding amounts or implementation timelines, instead focusing on changing the legal authority and restrictions around border security structures that states may already be considering or deploying.
