Independently verified. On March 22, 2023 (World Water Day) the renamed A. Donald McEachin Environmental Justice for All Act was reintroduced at a bicameral press conference. On the Senate side (S.919) the sponsor of record is Tammy Duckworth 'for herself, Mr. Booker, Mr. Markey...'; Booker is the first-named cosponsor. Booker did not merely cast a supporting vote: he co-led the Senate effort as co-chair/co-founder of the Senate's first-ever Environmental Justice Caucus, co-introduced the companion bill, headlined the press conference, and issued his own Senate press release titling him as an introducer and quoting him driving the effort. Because he actively led/co-led the legislation (beyond a single vote) but it died in the Committee on Environment and Public Works with no committee or floor vote and was never enacted, the correct outcome is CHAMPIONED, not FULL. ATTEMPTED is a weaker fit because there was no vote to cast; the action was the leadership/co-sponsorship itself. Same-standard fairness holds: a co-caucus-chair of either party who co-introduces and headlines a launch for a bill that dies in committee earns CHAMPIONED. Note: prior rating slightly overstated Booker as a formal lead sponsor; corrected here to co-lead/first-named cosponsor, which still supports CHAMPIONED. Outcome and confidence stand.
