Robert Levinson, a former FBI special agent who disappeared while traveling on Iran’s Kush Island in 2007, has “died while in Iranian custody,” his family announced Wednesday. ---SNIP--- “Those who are responsible for what happened to Bob Levinson, including those in the U.S. government who for many years repeatedly left him behind, will ultimately receive justice for what they have done,” the announcement said. That’s a reference to President Barack Obama’s administration, which did not secure Levinson’s release despite years of negotiating with Tehran in the lead-up to the implementation of the 2015 Iran nuclear deal.
