President Donald Trump gave a bizarre and ominous warning to reporters while taking pictures with the generals.

Here's a video of what he told reporters:

TRUMP: "Maybe it's the calm before the storm."

What did he say?

“You guys know what this represents," he said, smiling, "maybe it's the calm before the storm."

"What storm is that?" a reporter inquired.

"We have the world's great military people in this room, I will tell you that," he responded.

"And uh, we're gonna have a great evening, thank you all for coming," he added.

"What storm, Mr. President?" a reporter asked.

"You'll find out," he said, cryptically.

Where did he say this?

Trump was at a photo opportunity after a meeting with his military commanders at the White House.

What could he be referring to?

He could be referring to a retaliatory strike against al-Qaeda or Boko Haram militants in Niger, where a recent ambush took the lives of U.S. servicemen. Some conjectured he could have been meaning the ongoing tension with North Korea. Others believe he was hinting at a major operation in Afghanistan.
