WASHINGTON, May 30 (Reuters) - Oil could gush into the Gulf of Mexico from the BP BP.L. rig until August and the U.S. government is "preparing for the worst," Carol Browner, President Barack Obama's top adviser on energy and climate change, said on Sunday.
Speaking on the CBS TV show "Face The Nation," Browner said: "There could be oil coming up till August when the relief wells are done."
She said BP's latest effort to try to capture and contain oil would not provide a permanent solution or prevent some oil escaping into the sea even if the maneuver succeeded.
"We are prepared for the worst. We have been prepared from the beginning," she added. (Reporting by Alan Elsner, editing by Vicki Allen)
