WASHINGTON (AP) - A senator says he's willing to go to Iran if it would help find missing CIA contractor Robert Levinson.
    
Democratic Sen. Bill Nelson of Florida made the offer in a speech on the Senate floor Tuesday.
    
Levinson disappeared in Iran in 2007. For years, the government falsely said Levinson was traveling on private business. But he was really a CIA contractor traveling on an unauthorized mission to collect intelligence.
    
The U.S. has not had "proof of life" in years- Levinson's family last received photos and video of him in late 2010 and early 2011 - and is not sure who is holding him.
    
Nelson said if the Iranian authorities captured Levinson, someone in the government would know his whereabouts.
