The AP reported: The Obama administration blocked efforts by government scientists to tell the public just how bad the Gulf oil spill could become and committed other missteps that raised questions about its competence and candor during the crisis, according to a commission appointed by the president to investigate the disaster. In documents released Wednesday, the national oil spill commissions staff describes not an incidental public relations problem by the White House in the wake of the April 20 accident. Among other things, the report says, the administration made erroneous early estimates of the spills size, and President Barack Obamas senior energy adviser went on national TV and mischaracterized a government analysis by saying it showed most of the oil was gone. The analysis actually said it could still be there. By initially underestimating the amount of oil flow and then, at the end of the summer, appearing to underestimate the amount of oil remaining in the Gulf, the federal government created the impression that it was either not fully competent to handle the spill or not fully candid with the American people about the scope of the problem, the report says. The administration disputed the commission findings, saying senior government officials were clear with the public what the worst-case flow rate could be.
