Vance says details of US-Iran agreement still to be worked out amid scepticism from Republicans

Summary

JD Vance acknowledged that crucial details of a US-Iran agreement announced Sunday remain unresolved, as Republican senators voiced deep doubts about the deal ahead of its Friday ceremonial signing. Republicans demanded the White House release more information, particularly questioning whether the agreement includes funds for Iran and whether the Trump administration has adequately addressed their concerns. The disagreement among the president's own party suggests the accord faces scrutiny even before the formal signing ceremony.
