Dave Cooper, a former member of SEAL Team 6, which hunted down al-Qaida leader Osama bin Laden in 2011, was contracted to provide a threat assessment of the planned pipeline for NextGen Climate, led by a vocal Keystone XL opponent, billionaire Tom Steyer.
Portions of the report, obtained Wednesday in a redacted form by several media outlets, said Keystone is a ripe target for terrorists.
"A handful of terrorists could use just four pounds of explosives at each of the three pump facilities located [redacted] to cause explosions that could trigger a catastrophic spill."
Shawn Howard, a spokesman for Keystone XL planner TransCanada, told Huffington Post safety was a top priority for the pipeline.
Steyer, a former hedge fund manager, has pledged to help tip the scales in favor of Democrats who have made climate change a priority issue through funding from his climate change-focused SuperPAC NextGen Climate Action.
Keystone XL, which would cross the U.S.-Canadian border, needs a permit from the U.S. government before construction can begin.
