Thirteen years ago today, on March 9, 2007, Robert A. “Bob” Levinson was abducted on Kish Island, Iran. For 13 years, the Iranian government has denied knowledge of his whereabouts or condition, a claim that defies credibility.

Mr. Levinson’s family, including grandchildren he has never met, has borne an unimaginable burden of uncertainty and hardship throughout this time. Iran must honor the commitment it has made to work with the United States for Mr. Levinson’s return. International norms, respect for human rights, and basic human decency demand no less.

Returning all Americans held hostage or wrongfully detained abroad is President Trump’s top priority. We will work until Bob Levinson and all U.S. hostages and wrongful detainees come home.
