The Iranian delegation negotiating a peace deal with the US in Switzerland almost walked out after a barrage of President Donald Trump's social media posts.

Donald Trump said this week that, if the deal with Iran fails, he will blame J.D. Vance. He was only half-joking.

The vice president's neck is on the line if the deal doesn’t work out, Trump joked. And Trump said with a laugh that, if it is a success, he’ll take all the credit.
