pipeline

Billionaire and climate activist Tom Steyer intends to target voters who supported President Obama’s reelection bid in a new campaign to sharpen opposition to the Keystone XL oil sands pipeline.

Steyer said the arguments for building the Canada-to-Texas pipeline have “collapsed.” He said his NextGen Action political action committee would announce its new campaign June 20.

“Given that none of the chief arguments being put forth by supporters of the pipeline remain standing, NextGenAction is going to be working with our friends and allies who are opposed to the development of Keystone XL to intensify our efforts in communicating what is the right policy choice to your Administration,” Steyer said in an open letter to Obama that was obtained Monday by The Washington Post.

A number of left-leaning and green organizations that oppose Keystone have recently criticized Organizing for Action, a political group with roots in Obama’s reelection campaign, for not taking a position on the pipeline.
