Eighteen days into the standoff over his $5.7 billion wall-fence-barrier, Donald Trump is rolling out his heaviest weapons: a prime-time Oval Office address tonight and a visit to the Mexican border later this week. It’s the president’s personal Alamo. Inside the West Wing, Trump has told aides he’s prepared to stake his presidency on making a last stand. “He has convinced himself he can’t win re-election in 2020 unless he gets a lot of the wall built. It’s fundamental to his id,” a former West Wing official said. “The problem is, the Democrats know that.”

Trump’s aides fear he has given himself no way out. “The president put himself in a box,” the former official in touch with the White House told me. “The problem is there’s no endgame. Right now the White House is at a seven on the panic scale. If this thing goes on past the State of the Union they’re going to be at an 11.” Another prominent Republican close to Senate Majority Leader Mitch McConnell described Trump’s handling of the shutdown as “total fucking chaos.”

Acting chief of staff Mick Mulvaney, installed in the job just before Christmas, may already be looking at escape routes. Unlike his long-suffering predecessor, John Kelly, Mulvaney has indicated he’s prepared to walk away if things go south with the president. “Mick has both eyes open,” said a person who spoke with Mulvaney recently. “So far, Trump has been more DIY than ever before. It’s a continuation of where things left off with Kelly. Mulvaney is not going to stick around and get ground up.” Before Christmas, Trump’s former campaign manager Corey Lewandowski told people that Mulvaney wouldn’t last long, according to a person who spoke with Lewandowski. Last night, The New York Times reported Mulvaney is interested in becoming president of the University of South Carolina.

Meanwhile, Jared Kushner and Ivanka Trump have been underwhelmed with Mulvaney’s political skills, two people familiar with their thinking said. The sources said Jared and Ivanka have discussed recruiting Blackstone executive Wayne Berman to serve as White House strategist, but so far Berman hasn’t been interested a source familiar with his thinking said. Blackstone declined to comment.

The shutdown has pushed the Russia investigation out of the news cycle. But Trumpworld knows it hasn’t gone away. Rudy Giuliani recently told a friend that he expects Mueller’s report to be “horrific,” a person briefed on the conversation said (Giuliani did not respond to a request for comment). “You’re already hearing people speculate Trump could do a deal and resign.”

The White House did not respond to a request for comment.
