The U.S. president’s eldest son Donald Trump Jr. said Wednesday that he wouldn’t rule out a future run for the White House.

“Maybe one day … that calling is there,” Trump Jr. said at the Qatar Economic Forum in Doha. “I think my father has truly changed the Republican Party.”

Trump Jr. is considered one of the most prominent figures in the MAGA movement and is seen as a potential successor to his father’s political legacy, if not the top job.

He currently serves as executive vice president of the Trump Organization, but also helps shape his father’s second administration, ensuring that loyalists and ideological true believers populate the executive branch, while serving as a key Trumpian attack dog on social media.

Speaking at the Doha forum, Trump Jr. defended the administration’s approach — particularly on trade — arguing that it poses no threat to the strength of the U.S. economy. “Changes take time,” he said, adding that fears among U.S. citizens about Trump’s trade policies were largely fueled by “hysteria” in the media.

In March, Trump Jr. denied reports that he was considering running for president in 2028, pointing out that he was a key figure in getting his father to pick JD Vance as vice president, who he described as “an instant power player” in the Republican Party.

Trump the elder, despite being constitutionally barred from serving a third term as president, has himself stoked the idea that he could run again in 2028.
