Zarrab also admitted he spent more than a year in federal jails hoping to win release through a prisoner exchange with Turkey before deciding to cooperate, but denied that anger at Turkish officials for not doing enough to make it happen fueled his testimony about bribes to President Recep Erdogan's government.
