Iran's new supreme leader Mojtaba Khamenei shows signs of involvement in government affairs more than three months after his appointment, though he has not appeared in public.

Mojtaba Khamenei was appointed as Iran's new supreme leader following the death of his father and predecessor, Ali Khamenei, who was killed in an airstrike at the start of the U.S.-Israeli war against Iran.

Khamenei has not been seen in public since his appointment, his health condition remains unknown, and it is unclear how much power he currently wields.

U.S. President Donald Trump stated Wednesday that Mojtaba Khamenei was "involved, absolutely," while U.S. Secretary of State Marco Rubio said Tuesday "there are indications out there that he is increasingly engaging at some level."
