Filmmaker Michael Moore Under Federal Investigation

(Undated) -- Filmmaker Michael Moore is being investigated for alleged violations of a U.S. trade embargo following a trip to Cuba. Moore reportedly took 9-11 workers to the communist country to seek medical care and filmed the trek as part of a documentary examining the U.S. health care industry. In a letter sent to Moore, the Treasury Department said it has no record of Moore getting a license that authorized him to "engage in travel-related transaction involving Cuba."
