President Donald Trump dismissed a Vanity Fair story claiming that Melania Trump did not want to be the first lady.

The magazine story cited a “longtime friend of the Trumps” who claimed that the president’s wife never wanted to be first lady and did not think he would win the presidency.

“Melania, our great and very hard working First Lady, who truly loves what she is doing, always thought that ‘if you run, you will win,'” Trump wrote on Twitter on Tuesday morning. “She would tell everyone that, ‘no doubt, he will win'”:

Melania, our great and very hard working First Lady, who truly loves what she is doing, always thought that “if you run, you will win.” She would tell everyone that, “no doubt, he will win.” I also felt I would win (or I would not have run) – and Country is doing great! — Donald J.

The president did not call out Vanity Fair specifically but challenged the claims in the story.

“I also felt I would win (or I would not have run) – and Country is doing great!” he added.

On Monday, the first lady’s office denounced the story as untrue.

“Once again part of the liberal media, this time Vanity Fair, has written a story riddled with unnamed sources and false assertions,” a spokesperson for the first lady said in a statement to CNN’s Kate Bennett, adding:

As a magazine tailored to women it is shameful that they continue to write salacious and false stories mean to demean Mrs. Trump, rather than focus on her positive work as First Lady and a supportive wife and mother. As has been stated on the record many times before, she is honored by her role.

The first lady personally unveiled the White House Christmas decorations on Monday, hosting children for the occasion.
