All three cited sources are reachable and directly document this promise and outcome. (1) The merkley.senate.gov release confirms the April 18, 2023 introduction, identifies Merkley verbatim as "the ETHICS Act lead sponsor," and states the bill "would bar members of Congress, their spouses, and dependent children from owning or trading individual stocks, securities, commodities, or futures." (2) The HSGAC release confirms the July 24, 2024 committee advancement, identifies Merkley as lead sponsor with the bipartisan bill "built off of Merkley's ETHICS Act," and contains the verbatim Merkley quote "For the first time, a Senate committee considered and passed legislation to ban Congressional stock trading." (3) Roll Call confirms the 8-4 committee approval, that Merkley introduced the original measure and negotiated the revised version with Ossoff, Peters, and Hawley, and that the bill did NOT pass the full Senate or become law. This satisfies the CHAMPIONED leadership test: the record shows Merkley as lead sponsor/author and bipartisan dealmaker — active leadership, not a lone vote or passive support — while the promised enactment ("pass") did not occur. CHAMPIONED (led but not passed) is correct; it neither overstates (not FULL, since no passage) nor understates (stronger than ATTEMPTED/PARTIAL, given documented leadership) the evidence. Quotes were verified: the load-bearing phrases appear verbatim in the sources; the rating's rendering is lightly paraphrased/composited but not fabricated.
