Relating to the recovery by the attorney general from the federal government of certain border security expenditures.

HB 1543 requires Texas' attorney general to calculate and invoice the federal government for border security costs incurred by Texas during each state fiscal biennium. The bill mandates that the attorney general submit an annual invoice (with the first due by March 1, 2026) requesting reimbursement for border spending, capped at $20 billion for the initial recovery attempt. If the federal government doesn't pay within 6-8 months, Texas may sue to recover the funds, with any recovered amount deposited into the state's general revenue fund. This bill directly affects Texas' budget by creating a formal process to seek federal reimbursement for past border security expenditures.
