Officials believe all 64 people aboard the American Airlines flight and three people aboard the Army helicopter died. Here's what we know about the victims.

An American Airlines regional jet went down in the Potomac River near Washington, D.C.'s Ronald Reagan Washington National Airport after colliding with a U.S. Army Black Hawk helicopter on Wednesday night, with no survivors expected amid the extremely cold and windy conditions.

President Donald Trump called a plane crash that has left 67 people presumed dead an "hour of anguish" but later claimed diversity, equity and inclusion hiring policies could be responsible.
