Friends, I launched my campaign for Congress back in 2017, becoming one of the first House candidates in history to run on a climate platform.

Eight years later, I'm honored to announce that I've been selected as Climate Chair of the DCCC!

I, along with my friends and colleagues on the 2026 DCCC Leadership Team, have been tasked with defining Democratic priorities in the Trump era. 

Listen: I’ve been a bona-fide Climate Hawk since the day I entered Congress. No matter how angry it makes Trump and his Big Oil overlords, I won't ignore the giant melting glacier in the room.

While Trump’s goons dismantle the EPA, hand your tax dollars to fossil fuel CEOs, and scrub science from official communications, I’ll help Americans understand the climate crisis and how we can fix it together.

I’ll demand evidence-based policymaking, continue nerding out over climate and energy stats on Twitter, and, above all, make sure climate deniers don’t get the last word.

Will you help me give science a seat at the table? Become a Founding Member of my Climate Coalition by kicking in just $5 or $10 today.
