Iran reimposed Strait of Hormuz restrictions threatening a U.S. ceasefire deal as Trump rallies in Arizona with record-low approval ratings. Meanwhile, businesses prepare for Monday's $166 billion tariff refund portal launch, but consumers likely won't see money back. Iran's reimposition of Strait of Hormuz restrictions puts the ceasefire at risk, with negotiations hinging on whether the U.S. accepts Iran's five-year versus the administration's preferred 20-year nuclear enrichment pause. President Trump's approval rating has hit a record low of 39%, yet loyalist crowds at his Arizona megachurch rally show strong support, suggesting his strategy relies on mobilizing existing supporters rather than winning new voters.
