Carter is the first former president to announce his opposition to the controversial pipeline. Both George W. Bush and Bill Clinton have said they would support construction, according to the Washington Post.

The Keystone pipeline would export crude oil from tar sands in Canada to American refineries.

White House Press Secretary Jay Carney last week said that Obama would not establish a hard deadline for his decision on the pipeline, despite a letter from a group of Senate Democrats urging the President to approve the pipeline by the end of May.
