HCR 51 calls on the United States Congress to reimburse the State of Texas for the $11 billion spent since 2021 on border security efforts under Operation Lone Star. The resolution asserts that immigration enforcement is the responsibility of the federal government, but due to policies enacted by President Joe Biden's administration, Texas has faced unprecedented levels of illegal immigration, leading to significant financial and resource burdens. The resolution cites statistics from the U.S. Customs and Border Patrol, highlighting over eight million border encounters since January 2021. It emphasizes that Operation Lone Star, a collaborative effort between the Texas Department of Public Safety and the Texas Military Department, has successfully reduced illegal border crossings by 74%. Through this resolution, the Texas Legislature formally demands financial reimbursement for the state's expenditures in securing the southern border​.
