Fox:

The future of U.S. relations with Iran hinges on Tehran coming clean about the whereabouts of a former FBI agent who vanished a decade ago in the Islamic republic, Sen. Marco Rubio told Fox News.

Robert “Bob” Levinson disappeared in 2007 from Iran’s Kish Island, where the retired FBI agent had traveled on an unauthorized mission to recruit an intelligence source for the CIA. With the exception of a proof-of-life video in late 2010, there has been no credible sighting of Levinson or confirmation of who, specifically, is holding him and why. Iranian leaders deny knowing his whereabouts – a claim U.S. officials categorically reject.

"Bob Levinson went missing because of the Iranian regime,” Rubio, R-Fla., said Friday. “I believe with all my heart they know where he is, they know what’s happened to him and we should hold them completely and entirely responsible for his fate, his whereabouts and the outcome of this.”

“It should influence everything we do with Iran moving forward,” Rubio said. “How this case is handled up to this point and from this point forward will in many ways determine U.S. policy towards Iran.”
