Former Trump State Department senior adviser Christian Whiton joins 'Mornings with Maria' to weigh the prospects of President Donald Trump's Iran deal, warning key questions remain unanswered as negotiations continue.

Details of the agreement were not immediately released, but it appeared that it would not be implemented until it is signed.

Trump says a deal has been reached with Iran and he has authorized an end to the US naval blockade in Strait of Hormuz.

President Trump and Pakistan's prime minister announced Sunday night that the U.S. and Iran had completed a deal to end fighting in the Middle East. Mr. Trump also said the U.S. blockade on the Strait of Hormuz would end immediately.

Prime Minister Benjamin Netanyahu did not issue an immediate statement, but other Israelis disparaged the peace deal and said Israel’s fight against Hezbollah in Lebanon would go on.

Pakistan says the United States and Iran have reached an agreement to end the war and open the Strait of Hormuz, offering relief to the global economy more than three months since the war began. Full details of the deal were not immediately available.

President Trump on Sunday said on social media that a deal with Iran has been completed and that he's authorized the reopening of the Strait of Hormuz.

Israel’s defense minister said Monday that Israel won’t withdraw from land seized in Lebanon, potentially challenging an interim deal that Iran and the United States reached hours earlier that includes opening the Strait of Hormuz and further extending a shaky ceasefire.
