Trump, however, has repeatedly decried the deal, having described it as the “worst and most one-sided transactions” the United States had ever signed. Under a US law known as the Iran Nuclear Agreement Review Act, the president must write to Congress every 90 days to certify whether the White House believes Iran is abiding by the deal. After twice reluctantly certifying the accord, Trump has recently appeared to side with the foreign policy hawks in his administration. Should Trump refuse to certify Iran’s compliance, it would not necessarily mean an immediate US withdrawal from the pact, according to US political sources and observers. Instead, the law would allow Congress to decide within 60 days to reimpose some of the sanctions against Iran that were lifted under the deal.
