All three cited sources are reachable and support the rated outcome. (1) Senate roll call #372 confirms H.R. 1 (One Big Beautiful Bill Act) passed 50-50 with the VP breaking the tie, and that McCormick (R-PA) voted Yea — his vote was decisive; the quote "McCormick (R-PA), Yea" appears verbatim. (2) McCormick's official press release frames the bill as delivering border security; both quoted fragments ("to secure our nation's border and bolster our national defense to keep Americans safe" and "historic investments in the border, law enforcement, and defense") appear. (3) Times Leader confirms McCormick voted yes and quotes him on securing the border and bolstering national defense. This documents substantive, on-point legislative action on both prongs of the promise via an enacted bill that funds border-barrier construction and Border Patrol hiring. It correctly falls short of FULL because the promised end-states are not realized (wall funded but not "finished"; agent increase funded but hiring in progress). It is correctly not CHAMPIONED — the sources show a decisive supporting vote, not authorship or leadership of the border provisions. PARTIAL is appropriately calibrated and does not overstate the evidence. Note: the specific appropriations figures and the Laken Riley Act cosponsorship in the original rationale are not confirmed by these three sources, but they are not load-bearing to the PARTIAL rating, which rests on the verified decisive vote and the senator's own border-security framing of the bill.
