Former first lady Melania Trump confirmed that her son Barron Trump voted for his father in the presidential race against Vice President Kamala Harris.

“Voted for the first time – for his father!” Melania wrote in a post on X, formerly Twitter. Her post included a photo of Barron filling out his ballot.

Barron, the former president’s youngest son who turned 18 this year and is attending New York University, has not discussed politics publicly, unlike his siblings who have played a more active role in Trump’s administration and campaign .

Polls showed Trump had closed out a close race against Harris in the weeks leading up to Election Day, and the race was still too close to happen in most battleground states as of Tuesday evening. CNN hadn’t called North Carolina until 11:40 PM ET — before Trump. According to the polls of 538, the Republican won by 1.2 points on Election Day.

Trump previously told Fox News’ Maria Bartiromo that Barron was a factor in his decision to team up with popular streamer Adin Ross and Buses with the boys last month.

“A little,” Trump said. “He tells me about all the ‘hot’ guys, people I’ve never heard of. (He says) ‘Dad, that guy is hot.'”

Trump told Ross that his “sons told me about you.”

“They told me how big – Barron, he said, ‘Dad, he’s really big,’” Trump said.

Trump’s former chief of staff Mick Mulvaney previously said that Trump had asked Barron for advice on how to gain support from younger voters, a group that has historically leaned toward Democrats.

Because he just turned 18 this year, this is the first election in which Barron was allowed to vote.

Barron has not publicly entered the political sphere, although at one point it was announced that he would speak in support of his father at the Republican National Convention in Milwaukee. But in the end he wasn’t there.

“While Barron is honored to have been selected as a delegate by the Republican Party of Florida, he regretfully declines to participate due to prior commitments,” the former first lady’s spokeswoman said at the time.

Trump’s other sons, Donald Trump Jr. and Eric Trump, have been involved in his political career. His daughter Ivanka Trump served as a senior White House adviser but has largely stayed out of politics since leaving office in January 2021. Donald Jr. and Eric were prominent supporters of their father’s presidential campaign this year.
