The main purpose of this legislation, known as the Operation Lone Star Reimbursement Act, is to provide financial reimbursement to the State of Texas for costs incurred in securing the southern border of the United States. The bill recognizes that the federal government has a primary responsibility for border security but acknowledges that Texas has had to take significant measures to address border security issues due to perceived inaction by the federal government from January 2021 to January 2025.
