That has left foreign policy analysts wondering which Donald Trump is going to show up for his first foreign trip, which has him visiting five countries in the Middle East and Europe over nine days.
The trip, which includes stops in Saudi Arabia, Israel, Rome, Brussels and Sicily, will likely shine the biggest spotlight on Melania Trump to date.
The bilateral summit on Saturday comes with Saudi leaders rebuilding crucial ties with Washington after feeling that Trump's predecessor Barack Obama tilted too much toward Tehran. The Saudis have laid out a massive red carpet for Trump and his business delegation with multiple events.
"It's a combination of input that is sought from embassy on the ground, the (National Security Council), and the State Department", said Anita McBride, who served as chief of staff to first lady Laura Bush.
From Saudi Arabia, Trump will move on to Israel, where he will have meetings with Prime Minister Benjamin Netanyahu and meet Palestinian leader Mahmud Abbas in the West Bank.
Mrs Trump, a native of the central European nation of Slovenia, said she will spend time at her events speaking with women and children. The centerpiece of the president's visit to Brussels is now a tour of the new North Atlantic Treaty Organisation building, which will open in about a year. She also visited the National Museum of African American History and Culture with Sara Netanyahu.
The prince's foundation is hosting the forum where Trump is expected to deliver a speech to the Muslim world on Sunday.
"The President is going to the Middle East to let our friends know we are back and to let our enemies know we are back", said David Urban, who ran the President's successful Pennsylvania campaign and worked with his transition team, on CNN.
Trump declared Thursday that he's the subject of the "greatest witch hunt" in political history after former FBI Director Robert Mueller was named special counsel to oversee the investigation into the Trump team's ties to Russian Federation. But he also made clear he dislikes the decision to send weapons to a Kurdish faction.
The person was not authorized to be quoted by name discussing the details of the plan in advance of the formal announcement and spoke on condition of anonymity.
In fact, last year was the first time in 21 years the United States sustained a trade surplus with Saudi Arabia, mainly due to lower oil prices. Many White House aides have been hoping the trip will provide an opportunity for the young administration to refocus.
Like President Donald Trump, the trip overseas will be her first since her husband's inauguration in January.
"We are witnessing now a change in the tone, change in policy" from Trump, he said. Every first trip is over-scrutinized. Trump, in turn, has said he intends to push for $1 trillion in United States infrastructure investments over the next decade, with $200 billion coming from taxpayers and the rest from the private sector.
The success - or failure - of the first lady's first foray into foreign diplomacy is ultimately dependent on how safe she intends to play it. "He represents the United States, even if we are setting kind of a low bar for this trip - if he doesn't make mistakes". It is also where Fox's Baier is confirmed as a speaker.
