U.S. President Donald Trump has expressed doubt about whether Iran’s new Supreme Leader, Mojtaba Khamenei, is alive. In an interview with NBC News on Saturday, Trump said that no one has seen Khamenei so far and noted that the Iranian leader issued his first statement in writing rather than appearing on camera. Trump added that he has heard reports suggesting Khamenei may not be alive and remarked that if he is, he should act wisely for his country by surrendering.

When asked whether he supports any potential successor to Khamenei, Trump declined to name anyone. The comments come amid uncertainty surrounding Iran’s leadership transition and the lack of public appearances by the new leader.

The situation adds to ongoing speculation about Iran’s political stability following the leadership change, though no official confirmation regarding Khamenei’s condition has been provided.
