With roughly 24 hours to go before a memorandum of understanding with Iran is scheduled to be signed in Switzerland, Vice President JD Vance threw doubt on whether the historic ceremony will occur. 

The MOU outlines an agreement between the US and Iran to begin ceasing hostilities and begin negotiating an end to the three and half month long war. 

The agreement, which was signed by Donald Trump at the French palace Versailles sometime around Wednesday evening, immediately lifts sanctions on Iran's oil exports. 

It also calls for the free passage of ships through the Strait of Hormuz and the ending of the US Naval blockade on the area. 

Trump has said that Vice President JD Vance will oversee the signing ceremony in Lucerne, Switzerland, scheduled for Friday, noting this week 'This way, if it works out, I'm going to take the credit. If it doesn't work out, I'm blaming JD.'

Pressed on whether the trip will still occur on Thursday, Vance told reporters that he 'suspects' he will still go, casting doubt on whether he actually will. 

'I plan to go to Switzerland ... we think these technical negotiation areas start sometime this weekend. That's still the plan, but that could change because it's not an easy country, Iran, to get out of, and so we're trying to figure out exactly when that's going to happen,' Vance said. 

'I suspect this weekend, but I'm not sure,' he added. 'We're trying to figure that out as we speak, but again, I suspect it will happen this weekend.'
