A Sanders spokesman says that McKibben will speak at Sanders’ presidential campaign kickoff. In an email McKibben writes:
Bernie is the ultimate what-you-see-is-what-you-get politician. There’s no fancy moves and no adroit spin, just relentless day-in day-out advocacy for working people, and for a working planet. Bernie’s been in the forefront of all the crucial environmental fights of recent years, always willing to knuckle down and do the hard work of fighting the big corporations.
Ben Cohen and Jerry Greenfield, founders of Ben & Jerry’s Homemade Inc., are also expected to speak — with free ice cream in tow.
