All four cited sources are reachable and support the outcome. The two PRIMARY Hoeven press releases document genuine legislative leadership beyond a mere vote: source 1's exact quote is present verbatim and the page shows self-attributed active advocacy ("I've worked to secure funding to modernize our nuclear forces," "We've built Grand Forks into a leading hub for unmanned aerial systems," secured $55M for the Twining School); source 4 confirms he "successfully included provisions in the FY 2026 Milcon-VA funding bill... directing the Air Force to prioritize and fund security enhancements at Minot AFB's Weapons Storage Area, and develop a... construction timeline for Sentinel launch facilities" — inserting provisions from his Appropriations subcommittee seat is authoring/leading, the core of CHAMPIONED. The two SECONDARY outlets (Grand Forks Herald, KFGO) corroborate with the exact/near-exact quotes, though in softer "helped secure"/collective-"we" language. One weakness: source 3 (KFGO)'s quote is a stitched, ellipsis-joined reconstruction rather than a clean single verbatim quote — its endpoint fragments appear on the page but the bridging clause was not confirmed verbatim; this is not fabrication and does not sink the rating. Two of four sources are Hoeven's own press releases, but primary records are legitimate evidence of what he did legislatively and are corroborated by the secondary reporting. CHAMPIONED (active leadership: inserted provisions, secured named project funding, hosted defense officials) is substantiated over plain FULL. Confidence trimmed from 0.92 to reflect the source-3 quote-stitching and the self-sourcing of half the citations.
