U.S. President Donald Trump delivered a foreboding message Thursday night, telling reporters as he posed for photos with his senior military leaders that this might be "the calm before the storm."

White House reporters were summoned suddenly and told the president had decided he wanted the press to document a dinner he was holding with the military leaders and their wives.

Reporters were led hastily to the grand State Dining Room, where they walked into a scene of the president, his highest-ranking military aides and their wives posing for a group photo. The cameras clicked and they smiled. A joke was made about someone's face being tired. Live classical music played.

Then, Trump gestured to the reporters in the room.

"You guys know what this represents?" Trump asked. "Maybe it's the calm before the storm. Could be the calm, the calm before the storm."

"What storm Mr. President?" one reporter shouted. ISIS? North Korea? Iran?

"You'll find out," the president said.

During a proclamation signing ceremony in the Oval Office on Friday, Trump did not elaborate, saying, "You'll find out."

White House Press Secretary Sarah Huckabee Sanders did not shed more light on Friday when asked by reporters.

"We're never going to say in advance what the president's going to do," said Sanders.

"I wouldn't say he's messing with the press, I think we have some serious world issues here," she said at another point during the briefing.

The president on Thursday evening lauded the military group, including his defence secretary and chairman of the joint chiefs of staff, and said they would be discussing the most pressing military issues facing the country, including North Korea and Iran.

Trump said "tremendous progress" had been made with respect to ISIS, adding, "I guess the media's going to be finding out about that over the next short period of time."

Military options 'at a much faster pace'

He also denounced Iran, saying the country should not be allowed to obtain nuclear weapons, and offered another stark warning to North Korea's Kim Jong-un.

"We cannot allow this dictatorship to threaten our nation or allies with unimaginable loss of life," he said, vowing to "do what we must do to prevent that from happening and it will be done, if necessary. Believe me."

He also said that he expects those in the room to provide him with "a broad range of military options, when needed, at a much faster pace."

The administration, in its first nine months, has endured some fraught Fridays. Trump signed an executive order at the end of the workweek on Jan. 27 barring entry to the country for 90 days for many citizens of several countries. The first so-called travel ban led to a weekend of chaos at many U.S. airports.

As well, announcements of the imminent departures of White House Press Secretary Sean Spicer, adviser Steve Bannon and Health and Human Services Secretary Tom Price have taken place on a Friday.

This week has brought another published report of discord within the administration, involving Rex Tillerson, but the secretary of state strongly confirmed his commitment to the president's agenda and denounced the report.

As well, at an Alabama rally for a senatorial candidate on the evening of Friday Sept. 23, Trump went off a tangent involving NFL players kneeling during the playing of the national anthem, referring to any player that chose that protest as a "son of a bitch."

It precipitated a weekend of Trump tweets and a counter-response from the NFL, all while U.S. territory Puerto Rico was dealing with the devastating effects of Hurricane Maria, events Trump didn't publicly comment on until early the following week.

The Trump administration did announce on Friday a long-expected revision to Obama-era rules which would allow more employers to opt out of providing no-cost birth control to women for religious and moral reasons.

The rules require most companies to provide birth control as preventive care for women, at no additional cost. Under the Affordable Care Act, preventive services are supposed to be free of charge to employees and their dependents.

The Trump administration's revision issued Friday expands a religious exemption that previously applied to houses of worship, religiously affiliated nonprofit groups, and closely held private companies.

Corrections

  • An earlier version referred to the effects of Hurricane Irma on Puerto Rico. The sentence has been corrected to reflect that it was Hurricane Maria that devastated the Puerto Rican islands.
