All four cited sources are reachable and support the rated outcome; no quote is fabricated. (1) The PRIMARY Senate Finance release (June 4, 2018) contains the promise-defining quote verbatim — Wyden vows to "maintain my hold on Ms. Patelunas, and to block other nominations until this stonewalling ends" — over Treasury documents "related to follow-the-money issues and Russia" and Michael Cohen transactions. (2) Roll Call confirms he extended the blockade by placing a hold on a second Treasury nominee, Justin Muzinich, explicitly over Russia-linked documents (Cohen, Torshin, Butina); the cited quote appears as the opening of a longer verified sentence. (3) The Washington Examiner verifies the load-bearing phrase "until the department quits stonewalling our oversight requests" tied to Wyden's Muzinich hold; the rating's ellipsis rendering is a fair composite. (4) Wikipedia confirms the eventual 55-44 confirmation and Dec 12, 2018 assumption of office, the sole fact it is cited for. Because this is an action promise about Wyden's own conduct — which he fulfilled and personally led beyond a mere vote — and the leverage ultimately failed only via a majority cloture override outside his unilateral control (documents never produced), CHAMPIONED does not overstate the evidence and is more defensible than FULL. Rating upheld.
