This post has been updated below with news that Podesta will recuse himself from the Keystone XL decision.

President Obama is getting a new high-level adviser who cares a lot about climate change and doesn’t care much at all for the Keystone XL pipeline.

John Podesta is no stranger to the White House; he served as chief of staff to President Clinton. And he’s no stranger to the Obama team; he led the president’s transition into office after the 2008 election. Since then, he’s served as an “outside adviser,” The New York Times reports, and “has occasionally criticized the administration, if gently, from his perch as the founder and former president of the Center for American Progress, a center-left public policy research group that has provided personnel and policy ideas to the administration.”
