There have got to be better topics of debate than whether @elonmusk is committed to climate action. He has dedicated his career to the mission of replacing fossil fuels with clean energy & has strongly backed the Sierra Club's advocacy work. We are proud to have his support.
The Koch brothers have donated $900 million (that we know of) to conservative candidates in the last 10 years. So, no, $40k from someone worth $20bn is a not actually worth discussing. It’s a rounding error.
