The White House announced late Saturday that President Donald Trump will make a major statement Sunday morning, but did not give further details.
"The President of the United States will be making a major statement tomorrow morning at 9 o'clock (1300 GMT)," said White House deputy press secretary Hogan Gidley.
The news follows a tweet from Trump earlier in the evening in which he said: "Something very big has just happened!" He did not elaborate.
