Activist and former White House adviser Van Jones came out swinging against the Keystone XL pipeline Friday night on CNN, warning that if it’s approved it would be a big black mark on President Obama’s legacy. His comments came a few hours after the State Department released a draft environmental impact statement finding that the proposed pipeline wouldn’t have excessive environmental or climate effects. Jones:

What happens if you’ve got the Obama Pipeline — now it’s the Obama Pipeline — and it leaks? His legacy could be the worst oil disaster in American farmland history. …

If after he gave that speech for his inauguration, the first thing he does is approve a pipeline bringing tar sands through America … the first thing that pipeline runs over is the credibility of the president on his climate policy. …

The Obama Tar-Sands Pipeline should not the legacy of the president that gave that speech.
