All three cited sources were fetched and verified: every quote appears verbatim and each source supports the stated outcome. (1) Senate Roll Call #372 confirms Ricketts voted Yea on H.R.1 (the reconciliation bill enacted July 4, 2025 as OBBBA) on July 1, 2025 — a real, enacted expansion of domestic energy production, but as one supporting vote among ~50 with a VP tiebreak, not as author/driver (correctly NOT CHAMPIONED). (2) The Bipartisan Policy Center explainer confirms the OBBBA energy provisions verbatim ("Requires at least 30 offshore oil and gas lease sales in the Gulf of America over 15 years"), reinstated quarterly onshore lease sales, and pre-IRA royalty reversion — and notably contains NO discussion of consumer energy costs, corroborating that the "cut energy costs" half of the promise is unestablished. (3) The Ricketts press release confirms he introduced (with Klobuchar) the Renewable Fuel for Ocean-Going Vessels Act to "expand agricultural marketplaces, enhance American energy security" — genuine leadership, but on a narrow supporting bill, not the core production/cost promise. Because the production half was materially advanced through an enacted law and a sponsored bill, while the cost half has no documented outcome and his role on the flagship measure was a vote rather than leadership, PARTIAL is the accurate rating. (One immaterial imprecision: the rationale says onshore lease sales cover "nine western states" while the source says "ten"; this does not affect the outcome or any quote.)
