In his remarks, Gov. Mitt Romney implied that President Obama has blocked the Keystone XL pipeline extension from being built. But it’s a bit more complicated than that.

Referring to the project which aims to ship heavy crude extracted from Alberta’s oil sands to the U.S. Gulf Coast, Romney said, “Why the president said no to this pipeline, I will never know.”

In January, Obama did reject a presidential permit which would have allowed the pipeline to cross the U.S-Canada border, arguing his administration could not do the sufficient environmental and regulatory review in order to meet a congressionally-mandated Feb. 22 deadline

But it’s helped pave the way for TransCanada to build the southern segment of the pipeline from Cushing, Okla. to Port Arthur, Tex., by providing the needed Army Corps of Engineers permits. In fact, protesters including actress Darryl Hannah, are engaging in civil disobedience in Texas this week in an effort to halt construction of this section of Keystone XL
