After the Obama Administration made what appeared to be a number of huge cash payments as ransom money to release four American prisoners, the House Foreign Affairs Committee approved legislation to prevent future such payments being made without legislative oversight.

After the Obama administration transferred $400 million in cash to Iran, raising numerous questions relating to its purpose and whether it was a ransom payment for detained American hostages, House Republicans vowed to work to prevent another such ransom payment in the future.

A $400 million cash delivery to Iran to repay a decades-old arbitration claim may be unprecedented in recent US history, according to legal experts and diplomatic historians, raising further questions about a payment timed to help free four American prisoners in Iran.
