Activists say the plan to build a pipeline from Canada to the Texas Gulf Coast will hurt the environment.
Protester Becky Bond said, "That pipeline is going to bring some of the dirtiest stuff on earth across the United States down here to Houston where it can be refined and shipped to Asia and burned.
