President Barack Obama warned Wednesday there are “no guarantees” BP's latest attempt to plug the leaking well in the Gulf of Mexico will work.
Obama, speaking in Fremont, Calif., said if the “top kill” plan does not work, there are other “approaches that might be viable."
The “top kill” approach involves trying to plug the leak by
pumping thousands of barrels of very dense mud into the well.
The president on Wednesday reiterated that he has his top scientists and engineers working to stop the leak.
“We're going to bring every resource necessary to put a stop to this,” Obama said.
The president is set to unveil on Thursday the findings and recommendations of Interior Secretary Ken Salazar's 30-day review of offshore drilling safety before his visit to the Gulf on Friday.
Obama lamented the environmental damage that has already been done from the spill, and pledged his support for a massive clean-up effort.
"We will not rest until this well is shut, the environment is repaired and the clean-up is complete," Obama said.
