Facebook CEO Mark Zuckerberg's support for Keystone XL gets dislike from Elon Musk, Sierra Club, 350.org

Andy Kroll at Mother Jones reports that nine major environment and progressive groups, including Sierra Club, League of Conservation Voters and 350.org are "yank[ing] their current paid advertisements on Facebook or cancel future ad buys in protest of FWD.us, the dark-money nonprofit that Facebook CEO Mark Zuckerberg cofounded."

As part of its immigration strategy, FWD.us ran a week's worth of ads praising Sen. Mark Begich (D-Alaska) for supporting more drilling in the Arctic National Wildlife Reserve (ANWR) and featuring Sen. Lindsey Graham (R-S.C.) criticizing Obamacare and President Obama's stance on the Keystone XL pipeline. FWD.us ran the ads ostensibly to buy Begich and Graham some political cover to take a more moderate tack on immigration reform.

Helping provide politicians with political cover to more easily make controversial decisions is not an uncommon tactic among activists, but doing so by supporting environmentally-damaging policies was too much for Tesla Motors CEO Elon Musk and David Sachs.

Mike Isaac at All Things D broke the news that they were leaving the PAC.

Here's how Musk articulated why he decided to leave:

“I agreed to support Fwd.us because there is a genuine need to reform immigration. However, this should not be done at the expense of other important causes,” Musk said in a statement to AllThingsD. “I have spent a lot of time fighting far larger lobbying organizations in D.C. and believe that the right way to win on a cause is to argue the merits of that cause. This statement may surprise some people, but my experience is that most (not all) politicians and their staffs want to do the right thing and eventually do.”

With Musk's active role in advancing electric cars and solar power, it is nice to see him taking a stand on this issue.
