BRUSSELS, - The United States continues in its efforts to have American businessman, Robert Levinson, found and freed after having disappeared in Iran a year ago. State Department Deputy Spokesman, Tom Casey stated, "We do tend to use our Swiss channel fairly actively on the case of Mr. Levinson as well as other matters. Certainly, I would hope if she had an opportunity, she might suggest to them that they would be a little – be well-served to be a little more forthcoming and helpful to the Levinson family. It’s a basic humanitarian issue."
