PresidentDonald Trumpand First LadyMelania Trumphad a disagreement at dinner while atMar-a-Lagothree weeks ago and could not keep it from public view, according to an eyewitness.
“Melania was upset and they had words with each other over something,” the source tells PEOPLE. The couple was eating together in the club’s dining area on March 30.
It remains unclear what the issue was, according to this source.
Ivanka Trump, the president’s eldest daughter, and her husband,Jared Kushner, dined that night at a separate table, the source says.
Mrs. Trump’s spokeswoman, Stephanie Grisham, disputed the witness’ account as “completely false” but did not elaborate — instead telling PEOPLE, “I’d encourage the anonymous source to say such things on the record.”
(White House Press Secretary Sarah Sanders did not comment.)
The president and Mrs. Trump, who are parents to sonBarron, 13, regularly travel to Mar-a-Lago, in Palm Beach, Florida, on the weekends.
On March 30, the president spent much of the afternoon golfing and then spoke at a Republican fundraiser that night.
Curiosity about the Trump marriage has flared in the past, as when hetried and failedto hold her hand in front of the press or when multiple womenaccused himof being unfaithful. The president denied those allegations.
Mrs. Trumpsaid in an interview last yearthat she was not fazed.
“It is not a concern and focus of mine,” she told ABC News. “I’m a mother and a first lady and I have much more important things to think about and to do. I know people like to speculate and the media like to speculate about our marriage.”
“It’s not always pleasant, of course,” Mrs. Trump said. “But I know what is right and what is wrong and what is true or not true.”

On March 22, about a week before the witness saw the Trumps fighting, Muellerconcluded his investigation.
Within days, the attorney general released afour-page summary of Mueller’s conclusions, including that he did not find that anyone on Trump’s team conspired or coordinated in the Russian election interference.
The president declared it a “total exoneration,” and a White House spokesman told reporters on March 24 that Trump was “in a really good mood” over Mueller’s findings.
The Trump familyreturned to Mar-a-Lago for Easter, including daughterTiffany Trumpand eldest sonDonald Trump Jr.
But Mueller was not totally forgotten.
