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.
