Hundreds of Keystone XL pipeline opponents arrested at White House

More than 500 protesters chanting, “Hey, Obama! We don’t want no pipeline drama,” marched to the White House Sunday, demanding that President Obama stop construction of the Keystone XL pipeline extension that would daily carry 830,000 barrels of crude oil from Canada to the Gulf Coast. About 200 protesters, who marched from Georgetown University, through the streets of D.C., stopping in front of the house of Secretary of State John Kerry to drop “a fake oil spill,” were arrested after they used plastic zip ties to lock themselves to the White House fence. “We are here to tell President Obama to stop a pipeline that he has the control to stop,” said Justin Filtz, 26, who traveled from Stevens Point, Wisc. “The XL pipeline is like a line in the sand if we are going to stop climate change.” The segment of the Keystone XL pipeline that would run from Canada to Oklahoma would require a presidential permit.

Why does the President have this authority?  The Congress delegated it to him.
