The U.S. has said it is prepared to have talks with Iran and other parties involved in the 2015 Iran nuclear deal, from which former President Trump unilaterally withdrew. The U.S. has said it would return to the agreement if Tehran came into full compliance, though Iran has repeatedly said the U.S. must first lift all sanctions imposed by Trump. On Thursday, the Biden administration lifted travel restrictions for Iranian diplomats to the U.N. in New York City.
