Adversarial re-check: the outcome CHAMPIONED and confidence 0.8 hold, but two claims in the prior rationale could not be substantiated and were removed from the source set. VERIFIED: (1) Sen. Ted Budd's official Senate press release on the Build the Wall Now Act is live and states verbatim 'The House version of the bill is led by Rep. Jim Banks (R-IN)'; the bill mandates restarting border wall construction within 24 hours and unlocks roughly $2.1 billion in previously appropriated but unspent wall funding. Leading the House companion of a barrier-construction bill is affirmative leadership, not a single supporting vote, which is the CHAMPIONED threshold. (2) Banks's own Senate press release dated July 1, 2025 confirms he voted to pass the One Big Beautiful Bill Act, which the record shows provides $46.5 billion for a wall on the U.S.-Mexico border and was signed July 4, 2025 after a 51-50 Senate vote. (3) A July 13, 2026 Banks press release confirms continued cosponsorship of border-enforcement bills - the Mandatory E-Verify Act, the Detention Authority Clarification Act, and the BACK OFF Act. (4) The 'Remain in Mexico' half of the promise was reinstated by Executive Order 14165 sec. 6 on Jan. 20, 2025 and confirmed operational by DHS on Jan. 21, 2025 - consistent with the policy he advocated, but executive action Banks did not himself drive; no Banks-sponsored vehicle codifying MPP was located. CORRECTIONS TO PRIOR RATING: the prior rationale attributed sponsorship of a 'Border Security is National Security Act' to the July 2026 press release - that page lists three different bills and does not support the claim; and the prior rating's claim that the Immigration Accountability Project ranked Banks the top senator on immigration could not be verified. Both were dropped, and one quote on the third source was replaced with the text actually on the page. NEUTRALITY TEST: a legislator of either party who led the House companion of a bill advancing their promised policy (bill not enacted) and then voted for an enacted appropriation funding it would score CHAMPIONED. Not FULL, because the barrier is funded and under construction rather than built, and the MPP reinstatement was executive action rather than something Banks delivered. Not PARTIAL or ATTEMPTED, because he did more than cast a supporting vote - he led legislation.
