The US government has launched a probe into whether film director Michael Moore broke US laws when he went to Cuba for a new movie about US health care.
The US Treasury Department has written to the director warning him that "US citizens face civil and or criminal penalties for unauthorised travel to the communist country."
The letter also states federal concern that Moore travelled to Cuba in March without approval and asked for detail about travel dates, people on the trip and reasons why he might qualify for a journalist's licence to go to Cuba.
A spokesman for Moore declined comment on what the filmmaker was doing in Cuba, but said news reports about his taking victims of the September 11 attacks on New York's World Trade Centers there for health care were inaccurate.
