Speaking before an afternoon dip with his daughter, Obama said his administration remains committed to ensuring a full clean-up is carried out.
“I’ll not be satisfied until the environment has been restored, no matter how long it takes,” Obama said in Panama City Beach, Florida.
“We’re going to continue to monitor and remove any oil that reaches the surface.”

The trip came as BP’s attempts to permanently seal off the well that caused the devastating oil leak have suffered a setback.

BP has had to suspend work on the relief well and bottom-kill procedure until further tests are completed.
The firm is expected to finish its analysis tomorrow and says its driller rig is on standby to carry out the work.
