Wang, a Princeton University PhD student, was conducting research in Tehran when he was arrested there on espionage charges in August 2016. Iran released Wang in a prisoner swap between the two countries, with the US freeing Iranian scientist Massoud Soleimani. The White House announced Wang's release in a statement that thanked the Swiss for their assistance in negotiating with Iran. Iran accused Wang of being "sent" by Princeton to "infiltrate" the country, charges which the university says are "completely false." That's what Mr. Wang wants, and that's what we want for him, what the President wants for him," the senior administration official said.
