On April 20, 2010, an explosion destroyed an offshore drilling rig at the Macondo Prospect in the Gulf of Mexico, causing a major sustained oil leak. Obama visited the Gulf, announced a federal investigation, and formed a bipartisan commission to recommend new safety standards, after a review by Secretary of the Interior Ken Salazar and concurrent Congressional hearings. He then announced a six-month moratorium on new deepwater drilling permits and leases, pending regulatory review. As multiple efforts by BP failed, some in the media and public expressed confusion and criticism over various aspects of the incident, and stated a desire for more involvement by Obama and the federal government.
