A federal panel has revealed the Obama administration deliberately prevented government scientists from disclosing the full extent of the BP oil spill. On Wednesday, the national oil spill commission released documents showing the White House budget office denied a request to make public the National Oceanic and Atmospheric Administration’s worst-case estimate for the spill size. Despite receiving internal warnings the well was spewing between 2.7 million to 6.8 million gallons of oil a day, government officials repeatedly publicized a figure of 210,000 gallons a day.
