Verified all three cited sources against the promise (Newsom directing regulators to require 100% ZEV new-passenger-vehicle sales in California by 2035). The two secondary sources were fetched directly and their cited quotes appear verbatim: American Public Power Association ("The California Air Resources Board last week approved a rule that requires all new cars and light trucks sold in California will be zero-emission vehicles (ZEVs), including plug-in hybrid electric vehicles, by 2035") and DieselNet (ACC II "by 2035 100% of new cars and light trucks sold in California will be 'zero-emission vehicles'"); both also confirm the rule "codifies the light-duty vehicle goals set out in Governor Gavin Newsom's Executive Order N-79-20." The CARB primary-source page bot-blocks automated fetching (HTTP 403) but is genuinely reachable (top web-search result) and its cited quote is confirmed verbatim in search results, along with the codification of EO N-79-20 and the year-by-year ramp (35% MY2026, 68% 2030, 100% 2035). The documented chain supports CHAMPIONED: Newsom signed EO N-79-20 on 2020-09-23 directing CARB to require the 2035 100% ZEV mandate, and CARB formally adopted Advanced Clean Cars II on 2022-08-25 enacting exactly that requirement. Newsom did not merely endorse — as Governor he initiated the mandate by executive order and drove the agency to codify it, which fits CHAMPIONED. The outcome does not overstate the evidence; the 2025 federal CRA revocation of California's waiver is outside Newsom's control and does not undo the completed action. Rating kept.
