President Donald Trump issued an unprompted, cryptic message Thursday after meeting with military officials at the White House, saying about the gathering, “Maybe it’s the calm before the storm.”

“We have the world’s great military leaders in this room,” Trump said to reporters after uttering his remark during a photo-op in the Cabinet Room of the White House.

Pressed on what he meant, the president said, “You’ll find out.”

The president participated in a briefing Thursday evening with senior military leaders and their spouses, according to a schedule released by the White House.
