As the ink dries on the new Iranian nuclear deal, President Obama moved today to push the Middle Eastern nation to help return former FBI agent Robert Levinson, who disappeared in Iran's Kish Island in 2007.

"Today, Mr. Levinson becomes one of the longest held Americans in history," said a White House statement. "As we approach the upcoming holiday season, we reiterate the commitment of the United States Government to locate Mr. Levinson and bring him home safely to his family, friends, and loved ones. We welcome the assistance of our international partners in this investigation, and we respectfully ask the Government of the Islamic Republic of Iran to assist us in securing Mr. Levinson's health, welfare, and safe return."

Levinson disappeared in March 2007 after he traveled to Kish Island off Iran's southern coast. The 65-year-old is a retired 28 year veteran of the FBI and DEA who was in the country as a private investigator.
