The Trump administration is facing criticism for providing temporary sanctions relief for Iran’s crude, products and petrochemical sales as part of a 14-point memorandum of understanding (MOU) signed last week, under which both sides promised to end their effective blockades in the Strait of Hormuz. The extendable 60-day framework covers ongoing negotiations over Iran's nuclear program, but Tehran has already pushed back on Washington's insistence that International Atomic Energy Agency (IAEA) inspectors return to Iran. The US Congress, meanwhile, may have some recourse to block the MOU and a final deal, but this is not easily achievable.
