Aircraft was doing 'everything right' - Trumppublished at 16:47 Greenwich Mean Time
Trump says he has heard "tapes" - an apparent reference to recordings of air traffic control at the time of the incident.
He says the airliner was "doing everything right" and on the usual "track", but that "for some reason" the helicopter was at the same height and "going at an angle that was unbelievably bad".
"You had a pilot problem from the standpoint of the helicopter," the president says, without specifying what that "problem" was. He adds: "It was a very clear night."
He says he thinks more tapes will be released with visuals of the incident.
Trump then says the helicopter had the ability to stop, go up or down, or turn - "the turn it made was not the correct turn, obviously," he says.
