California's climate change law backer donates $5 million to fight Prop 23

McClatchy reports:

Thomas Steyer, a San Francisco hedge fund manager and a big backer of Democratic candidates, will donate $5 million to a group opposing the ballot measure to roll back California's landmark climate change law.

Steyer, founder of Farallon Capital Management LLC, has joined George Shultz, former U.S. secretary of the state, as co-chairman of the No on 23 committee, giving the group's leadership a bipartisan mix.
