The US president has paid his fifth visit to the country’s BP oil spill region.
Barack Obama made the weekend trip to Panama City, Florida, as part of a drive to encourage more tourists to do likewise.
He vowed to restore the economy and the regional environment in the wake of the Gulf of Mexico oil platform disaster which began on April 20.
“The well was capped. Oil is no longer flowing into the Gulf,” Obama said. “It has not been flowing for a month. And I am here to tell you that our job is not finished, and we are not going anywhere until it is. Beaches all along the Gulf coast are clean; they are safe and they are open for business. That is one of the reasons Michelle, Sasha and I are here.”
The Macondo well was provisionally capped on July 15.
The government was criticised over how it allowed BP to handle the emergency.
The British company has set aside $20 billion (16bn euros) for damages claims.
