U.S. President Donald Trump on Friday signed an executive order seeking to rename the Pentagon from the Department of Defense to the Department of War, and said he would ask Congress to make the change official.

"I think it sends a message of victory. I think it sends a message of strength, very strong, much stronger than anyone would really understand," Trump told reporters in the Oval Office.

The U.S. president said he would work with Congress to codify the change, but claimed it is unclear if lawmakers would have to act to make it official.

"We're going with it very strongly. There's a question as to whether or not they have to, but we'll put it before Congress," he said.

Meanwhile, Trump also warned Caracas that its jets would be shot down if they threatened U.S. forces, after Washington said two Venezuelan military planes buzzed an American naval vessel.
