US President Barack Obama has launched a stinging attack on BP chief Tony Hayward over the Gulf coast oil disaster.
Mr Obama focused his attack on some of Mr Hayward's remarks, which included saying that "I want my life back" and that the Gulf was "a big ocean" and that "the environmental impact of this disaster is likely to be very, very modest".
"He wouldn't be working for me after any of those statements," Mr Obama said.
The salty words, part of the his efforts to telegraph to Americans his engagement with the crisis, came in an interview with NBC television's Today show.
Mr Obama said he had been talking closely to Gulf Coast fishermen and experts on the catastrophic oil spill "so I know whose ass to kick".
And he strongly defended his role in dealing with the crisis that began with the April 20 explosion on a BP-leased oil rig in the Gulf, killing 11 workers.
"I was down there a month ago before most of these talking heads were even paying attention to the Gulf," Mr Obama said.
Some have criticised the president for not engaging passionately enough on the spill. Earlier, Mr Obama sought to reassure the nation that the Gulf would "bounce back" from the disaster.
