(NEWS CENTER Maine) -- President Donald Trump will address the nation after one of the deadliest mass shootings in history.
A former Marjory Stoneman Douglas High School student opened fire with a semiautomatic rifle at a Florida high school Wednesday, killing at least 17 people and sending scores of students fleeing into the streets in the nation's deadliest school shooting since a gunman attacked an elementary school in Newtown, Connecticut.
President Trump is expected to make comments about the shooting.
