Trump was slated to spend the day speaking by phone to staff and lawmakers, one White House official said. In the meantime, it remained unclear how long he would let the longest shutdown in the nation’s history drag on or whether he planned to declare a national emergency in the coming weeks to secure the funding he has demanded for a wall at the U.S.’s southern border, according to four advisers and staff reached by POLITICO.

“No one knows what he will do, and the president has not decided yet, so it keeps everyone guessing,” said one Republican close to the White House. “This could go on another week and he could declare an emergency, or this will go on until February.”
