WASHINGTON—JD Vance, the US vice president, has become the face of the tentative peace agreement with Iran, despite fierce criticism from hawkish Republican lawmakers.
Vance, a potential presidential candidate, has taken a risky position by defending the deal, which has come under fire for offering a financial lifeline to Tehran and sacrificing a major point of leverage over Iran.
As the lead public defender of the accord, Vance has faced intense scrutiny, with some Republicans questioning whether he is the right person to bring the conflict to an end.
The administration has roughly two months to negotiate the thorny details with the Islamic Republic, including a plan to prevent the country from developing a nuclear weapon.
Vance was appointed by President Trump to be the highest-ranking negotiator on the deal, but Trump has appeared to set up Vance to take the fall if the agreement falls apart.
The deal has sparked a heated debate, with some Republicans warning that giving billions of dollars to the Iranian government could be a bad idea.
