"The Department of State did not issue a permit for the Keystone XL pipeline while Clinton served as secretary of State. Environmentalists suspected Clinton supported the project and was preparing to award it the administration’s stamp of approval. But that didn’t happen before Clinton left the administration and former U.S. Sen. John Kerry was tapped for secretary of State.

In fact, in 2012, Clinton's Department of State recommended President Barack Obama deny the Keystone KL pipeline after Congress set a 60-day deadline for the administration to review the project. However, that decision was rooted in the time constraints and not the merits of the pipeline plan itself.

"The president concurred with the department’s recommendation, which was predicated on the fact that the Department does not have sufficient time to obtain the information necessary to assess whether the project, in its current state, is in the national interest," the State Department said in January 2012."
