Vice President JD Vance acknowledged on Tuesday that “a number of issues” with the US-Iran agreement still need to be resolved, as Republican lawmakers expressed deep skepticism and pressed the White House for more details about the deal brokered by President Donald Trump.
The memorandum of understanding, announced Sunday, aims to end the war in Iran by reopening the Strait of Hormuz and lifting the US naval blockade in exchange for financial incentives tied to Iranian compliance with specific benchmarks. A ceremonial signing is scheduled for Friday in Geneva.
Senate Republicans have raised concerns about unanswered questions regarding the deal’s scope and enforcement mechanisms. Some have focused on the inclusion of funds for Iran, questioning whether such incentives could be redirected toward malign activities despite administration assurances.
The White House has not released the full text of the MOU, fueling bipartisan demands for greater transparency. Critics argue the lack of detail undermines congressional oversight and could weaken US leverage in negotiations.
Analysts suggest the political trajectory remains uncertain, with internal GOP divisions threatening the deal’s long-term viability. The administration faces pressure to provide concrete benchmarks and verification measures before the ceremonial signing.
