Gas and oil continue to leak at the Deepwater Horizon oil spill site in the Gulf of Mexico in this frame grab captured from a BP live video feed June 22, 2010. The White House is set to step up its legal battle to keep deepwater drilling on hold in the Gulf of Mexico after oil companies persuaded a U.S. judge to overturn a six-month ban. Interior Secretary Ken Salazar said late on Tuesday he would order a new moratorium "in the coming days" to reinstate a temporary ban aimed at ensuring offshore safety after the worst oil spill in U.S. history struck at a BP operation on April 20.
