Siamak Namazi has been in prison in Iran for more than seven years. He's a dual US-Iranian citizen; one of three to be held inside Evin prison. He made an emotional appeal to President Biden to secure his release in a telephone interview with CNN's Christiane Amanpour. He shared his anguish over how he feels he's been treated by successive US administrations.

The 91福利社's Tim Franks spoke to his brother, Babak, and asked him what he took from Siamak's words.
