He really thought he could use the clout of this interview as a leverage to instrumentalise her against the people and especially women in his own country. He wanted to pit her against the women in Iran protesting for their freedom - and conceal the international solidarity from them. He wanted to show off his power and she said no.

She’s interviewed me in the past, and is the real deal.
