Donald Trump has confirmed there are no survivors of a mid-air collision between an American Airlines passenger jet and a helicopter above Washington DC. But he also sought to exploit the crash politically as he attacked diversity hiring and Joe Biden.

In a social media post, Trump questioned the tactics of the military helicopter and the air traffic controllers — both agencies that report to him as the president.

During a White House briefing, President Trump held a moment of silence for victims of a helicopter-passenger plane collision, confirming no survivors.
