President Obama has rejected the Keystone XL oil pipeline in one of the environmental movement’s biggest victories to date. After years of review and one of the largest grassroots campaigns in decades, Obama announced Friday he will not allow Keystone on his watch.

President Obama: “America is now a global leader when it comes to taking serious action to fight climate change. And frankly, approving this project would have undercut that global leadership. And that’s the biggest risk we face: not acting.”

The Keystone pipeline would have sent 830,000 barrels of crude oil every day from Alberta’s oil sands to refineries on the U.S. Gulf Coast. We’ll have more on the pipeline’s defeat later in the broadcast.
