The Biden administration has cleared the way to release $6 billion in Iranian oil revenue blocked by U.S. sanctions in exchange for five Americans imprisoned in Iran. Five Iranian nationals currently imprisoned in the U.S. are also being released as part of the agreement. Iranian officials will be allowed to use the funds to buy food, medicine and other humanitarian needs. Republicans have fiercely criticized the deal. Senator Tom Cotton of Arkansas accused President Biden of “paying ransom to the world’s worst state sponsor of terrorism.”
