Former Hostages Urge Biden Not to Deal with Iran Unless it Frees Other Americans Michael Lipin WASHINGTON - Two Americans and a U.S. permanent resident whom Washington says were held hostage by Iran for years until it freed them during the term of former President Donald Trump have urged his successor Joe Biden not to make gestures toward Tehran until it frees other U.S. hostages. In messages to VOA Persian in recent days, U.S. Navy veteran Michael White, Chinese American researcher Xiyue Wang and Lebanese U.S. permanent resident Nizar Zakka said Iran's release of its remaining American hostages should be a precondition for any U.S. negotiations or concessions to Tehran under President Biden, who took office last week. .
