Family of American missing in Iran plans Florida rally

The family of a former FBI agent who disappeared in Iran nine years ago while on a CIA mission is holding a rally demanding that the U.S. government keep pushing for his freedom.

The family of 67-year-old Robert Levinson is holding the rally Saturday near his South Florida home. He disappeared from Iran's Kish Island in March 2007.

A 2013 Associated Press investigation revealed that he was working for the CIA on an unauthorized intelligence-gathering mission to glean information about Iran's nuclear program.

If Levinson remains alive, he has been held captive longer than any American. Levinson's whereabouts and captors remain a mystery. U.S. officials believe the Iranian government was behind his disappearance. It has denied that.
