All three cited sources are reachable and every quoted string appears verbatim, so the rating survives adversarial verification. (1) Senate Roll Call Vote 570 (PRIMARY) confirms McCormick (R-PA) voted Yea on S.2296, the FY2026 NDAA, which passed the Senate 77-20 on Oct 9, 2025; quote "McCormick (R-PA), Yea" is present. The roll-call page alone documents only the vote, not the bill's DEI content, so I independently confirmed via Congress.gov and Senate Armed Services materials that S.2296 does eliminate DOD DEI offices, the Chief Diversity Officer position, diversity goals, and related training — making the Yea vote a genuine supporting action toward the "particularly in the military" component (a supporting vote, not authorship/leadership; the provisions were led by Sen. Banks). (2) The McCormick/Fetterman joint statement (PRIMARY) contains the exact sentence "We fully support the EEOC investigations into Title VII discrimination." and backs a federal probe into anti-Jewish discrimination at UPenn — directionally supportive of the antisemitism leg, though it is an EEOC Title VII employment matter, not the promise's actual university-funding-contingency mechanism (the page does not tie funding to antisemitism). (3) The American Jewish Congress guide (REPUTABLE_SECONDARY) confirms "co-sponsored the Antisemitism Awareness Act (S.558)," a bill not yet enacted. Net: real, recorded actions on both legs of a multi-part promise (a supporting NDAA vote that advances military-DEI elimination; a cosponsorship plus a supportive statement on antisemitism), but no enacted full outcome and no leadership — which correctly keeps this below FULL and CHAMPIONED and above ATTEMPTED. PARTIAL does not overstate the evidence. No conflation with Rep. Rich McCormick (R-GA); all three sources reference Sen. Dave McCormick (R-PA). Confidence held at 0.6, reflecting the borderline PARTIAL/ATTEMPTED line and that Source 2 is tangential to the precise funding-contingency mechanism.
