President Donald Trump flew to the island of Puerto Rico Tuesday to meet with its leaders for the first time since a powerful storm hit the U.S. territory two weeks ago. Trump and his wife Melania landed at an air base near San Juan, the Puerto Rican capital. Aid workers are using the base to direct recovery efforts on the Caribbean island. “I’ve never seen people working so hard in my life,” Trump said. The Trumps met with U.S. troops, emergency medical crews and survivors of Hurricane Maria. The storm was the strongest to hit Puerto Rico in many years. Maria destroyed its electric power network, as well as many homes, businesses, roads and farms across the island. At least 16 people were killed. Trump noted the island's relatively low death toll compared with another storm, Hurricane Katrina, which struck the southeastern United States in 2005.
