President Donald Trump once again spoke of a "calm before the storm" in Washington, D.C. 

The original comment last night raised eyebrows as Trump posed for a picture with senior military leaders and called the gathering “the calm before the storm.”

When pressed on what he meant by reporters, Trump only said "you'll find out," prompting speculation that Trump would de-certify the Iran nuclear deal or that it was related to North Korea. 

In the Oval Office this afternoon, Trump signed a National Manufacturing Day proclamation and again teased about the "calm before the storm."

As the event ended a reporter shouted to him to ask what he meant by the cryptic "calm before the storm" remark.

"You'll find out," he again stated, winking at the reporter and saying "thank you very much."

White House Press Secretary Sarah Sanders declined to elaborate on the remarks at her briefing Friday afternoon, only saying the president has repeatedly said that protecting the American people is his "#1 priority."

"If he feels action is necessary, he'll take it," she said. 

Watch the moment above.

On "The Story," Brit Hume reacted to the comment, saying Trump is known to drop hints like this and seems to "enjoy the befuddlement" that comes afterwards. 

Hume guessed the remark was related to North Korea military action, though he pointed out that experts have always said an attack on Pyongyang is not a good option because of the threat to South Korea.

"Who knows? And doesn't he love to keep us guessing," he noted.

Members of the White House press corps said they were summoned by the president as he gathered for a dinner with military leaders and their wives in the State Dining Room. 

"We have the world’s great military people in this room, I will tell you that," Trump said.
