Last Wednesday, the Obama administration officially denied approval of the Keystone XL pipeline. A rider included by the GOP in the payroll tax plan President Obama signed last month required the Administration to decide on the pipeline within a 60-day window.

In rejecting the pipeline, the White House said “imposing an arbitrary 60-day deadline on this process would make it virtually impossible for an adequate review [of the pipeline] to take place.”

House Speaker John Boehner criticized the decision saying “President Obama is destroying tens of thousands of American jobs and shipping American energy security to the Chinese. [There’s] no other way to put it: the President is selling out American jobs for politics.”

What do you think of the Administration’s decision? Of the decision’s justification? How important is the Keystone XL pipeline, or projects like it, to the future of U.S. energy? What economic or national security implications do you see this decision having?
