Wall Street trips as Trump's travel curbs fuel uncertainty

Trump on Friday signed executive orders to suspend travel to the United States from seven Muslim-majority countries on grounds of national security. "The market is reacting negatively right now because of the uncertainty that it creates," said Robert Pavlik, chief market strategist at Boston Private Wealth. U.S. equities hit a series of record highs following Trump's election in November, encouraged by his promise of tax cuts and simpler regulations.
