Mother Jones' Josh Harkinson reports:

Political disagreements with the US Chamber of Commerce have prompted the San Francisco Chamber to drop out of a program that automatically enrolled many of its members in the national group.

"Given the controversy over the US Chamber's position on climate change," said San Francisco Chamber president Steve Falk, "I've decided to sever our participation in the partnership program."

MoJo also notes that the SF Chamber is one of the nation's ten largest.
