Donald Trump’s luxury hotel and casino company violated the U.S. trade embargo against Cuba by doing business on the communist Island under the Fidel Castro’s presidency, Newsweek reported on Thursday.

Trump Hotels and Casino Resorts paid an American-based consulting firm called Seven Arrows Investment and Development Corp. at least $68,000 in 1998 as part of an elaborate scheme to cover up cash the Trump company had spent in Cuba, the report said. The consulting firm had instructed Trump’s company to make expenses incurred by travel to Cuba look legal by linking them to a charitable effort.
