Deepwater Horizon led to new protections for US waters. Trump just repealed them.
Trump’s executive order voids an Obama policy that aimed to prevent oil spills.
The Deepwater Horizon offshore drilling rig exploded on April 20, 2010, killing 11 workers. Gas erupted into a massive fireball, and then the rig gushed 4.9 million barrels of crude oil into the Gulf of Mexico. It soon became the largest and most expensive marine oil spill in history, with an estimated $17.2 billion in damages to properties, fisheries, and tourism across the Gulf Coast.
