A New York Times report says that the American president has suggested unusual, and even illegal, methods for preventing illegal immigration at the southern border. Among Donald Trump’s reported proposals was a waterway along the U.S. border with Mexico that could be filled with dangerous animals like alligators and snakes. The newspaper also says the president suggested that American soldiers shoot migrants in the legs if they try to enter the US. Members of the president’s staff reportedly advised the president that such acts would be illegal. The article was adapted from a new book by two New York Times reporters, called “Border Wars: Inside Trump’s Assault on Immigration.” The Times says it based its story on interviews with more than 10 White House officials. Those officials met with Trump to discuss ways to stop illegal migration from Central America.
