In other campaign news, Democratic nominee Hillary Clinton said Thursday that Donald Trump appeared to violate U.S. law by attempting to do business in Cuba. Clinton was referring to an investigation by Newsweek that revealed a Trump company violated the U.S. embargo against Cuba in 1998, spending at least $68,000 during a secret business trip to Havana. The investigation also reveals that Trump had knowledge of top executives working to cover up the illegal expenditures.
