Iran Nuclear Deal Architect Javad Zarif Stepping Down
Mohammad Javad Zarif played a key role in Iran's 2015 nuclear deal.
Now, CNN reports Iran's foreign minister is about to resign.
Zarif wrote on his Instagram account, "I sincerely apologize for the incapacity to continue serving and all the shortcomings during the service." He added, "Be happy and upbeat." Zarif was the key architect in the landmark deal aimed at reining in Iran's nuclear program -- which US President Donald Trump withdrew from last year.
