“When do we beat Mexico at the border?” Trump asked the crowd at his announcement at his namesake Trump Tower in New York City. “They are not our friend, believe me…The U.S. has become a dumping ground for everybody else’s problems…When Mexico sends its people, they are not sending their best. They are not sending you. They are sending people that have lots of problems, and they are bringing those problems to us. They are bringing drugs and they are bringing crime, and they’re rapists.”
