On Tuesday, Adriano Espaillat made history when he was sworn in as the first Dominican American and first formerly undocumented immigrant in Congress. “It was always my aspiration to come to the U.S. Congress,” Espaillat told NBC Latino in a Facebook video posted Wednesday. The video shares a bit of the congressman’s background from his childhood in the Dominican Republic to the nation’s social climate (Civil Rights Movement, Vietnam War) when he arrived at nine years old.
