President Trump is receiving updates on the crash of a Marine Corps aircraft off the coast of Australia, a White House official said Sunday.

White House chief of staff John Kelly is "keeping the president apprised" on the crash of the V-22 Osprey, the official told a reporter traveling with the president in Bedminster, N.J., including "an outstanding question on the V-22 from this morning's gathering." The official did not elaborate on the "outstanding question."

The U.S. military's use of the V-22 Osprey has come under scrutiny in recent years, with nine fatalities reported in the past decade.

Officials called off the search for three Marines missing in the latest crash, which occurred as their aircraft was attempting to land on a ship during a joint training exercise and fell into the sea.
