David Vitter committee. In response to the April 2010 Deepwater Horizon oil spill at an offshore drilling rig in the Gulf of Mexico threatening the coast of Louisiana, Vitter introduced legislation along with Jeff Sessions of Alabama to increase the liability cap of an oil company from $75 million to its most recent annual profits (or $150 million if greater). In the case of BP, the owner of the oil lease, its liability would be $20 billion. Vitter later introduced an amendment that would remove the cap entirely for this particular spill. Competing Democratic proposals would have raised the liability to $10
Environmental impact of the Deepwater Horizon oil spill that the damage from the spill would rapidly resolve, three years into the recovery dolphins continue to die, fish are showing strange lesions, corals in the gulf have died and oil still remains in some marsh areas. Due to both its size and the way it was handled, there is little previous research to predict long-term effects. At the 2013 "Gulf of Mexico Oil Spill and Ecosystem Science Conference", oceanographer David Hollander presented data that showed as much as one-third of the oil released during the spill may still be in the gulf. Researchers described a phenomenon called "dirty blizzard":
