evidence: Climate action has run through Harris’s career for decades. As California’s attorney general, Harris sued big oil companies like BP and ConocoPhillips, and investigated Exxon Mobil for its role in climate change disinformation. While in the Senate, she sponsored the Green New Deal resolution. And as vice president, Harris made the crucial tie-breaking vote to pass Democrats’ historic climate bill. [...] Advocates say Harris’s record on climate couldn’t be more different from her Republican opponent, former President Donald Trump – a man who has vowed to pull the US out of its climate commitments and to "drill, baby, drill." [...] Whether on lead pipes or dispersing billions in climate funding, Regan said Harris is a leader who "doesn’t do surface – she digs in."
