U.S. President Donald Trump said he is “not happy” with the selection of Mojtaba Khamenei as Iran’s new supreme leader, according to remarks reported by Fox News.

Fox News anchor Brian Kilmeade said that the U.S. President has told him “I am not happy” when asked about the new supreme leader. 

Mojtaba Khamenei’s election as Iran’s new supreme leader came after Trump insisted that he should have a say in the new leader’s appointment. 

Hours earlier, Trump told ABC News that the next leader of Iran won’t “last long” if he doesn’t have approval from the White House.

Trump declined to comment to The Times of Israel on Mojtaba’s election, saying: “We’ll see what happens.”

Iran has named Mojtaba Khamenei to succeed his father Ali Khamenei as supreme leader. Mojtaba Khamenei, 56, is the second son of Ali Khamenei, who led the Islamic Republic for 36 years and was assassinated on February 28 in the ongoing U.S.-Israeli airstrikes.

The decision was made by a vote by the Assembly of Experts, a body of 88 Islamic clerics tasked with choosing the new supreme leader.
