US President Donald Trump is unhappy with the election of Mojtaba Khamenei as the new Supreme Leader of Iran.

"I am not happy," Trump told Fox News in this regard.

Mojtaba Khamenei is the son of the slain Supreme Leader of Iran, Ali Khamenei.

And in an interview with ABC News on Sunday, the US president had stated that the next Supreme Leader of Iran will not “last long” without the approval of the United States.
