U.S. President Donald Trump has come under sharp criticism from hardline members of his own Republican Party over a proposed agreement aimed at ending the war with Iran. The deal, which Trump described as mostly negotiated, has drawn opposition from lawmakers and former officials who argue it risks losing a historic opportunity to fully contain Tehran. Texas Senator Ted Cruz, South Carolina Senator Lindsey Graham, and Senate Armed Services Committee Chair Roger Wicker all voiced strong objections, warning that easing pressure on Iran could be disastrous.

Trump dismissed the criticism, saying the agreement is not yet finalized and insisting that his administration’s approach is the opposite of the Obama-era nuclear deal. He maintained that U.S. military blockades on Iranian ports will remain until the deal is signed. Kentucky Senator Rand Paul defended Trump, saying peace talks are a normal way to end wars.

The conflict began on February 28 when the U.S. and Israel jointly attacked Iran. The war has proven unpopular domestically, costing U.S. taxpayers billions and disrupting global oil markets after Iran closed the Strait of Hormuz. Former officials Mike Pompeo and John Bolton also criticized the deal, while Secretary of State Marco Rubio defended Trump’s stance.
