On Monday, US President Donald Trump shrugged off the possibility of peace talks with Iran failing, telling CNBC: “I don’t care if they end, to be honest.”

“I really don’t care. I couldn’t care less,” Trump told CNBC’s Eamon Javers in a phone call at noon Monday, adding that he felt the protracted negotiations were “getting very boring.”

Trump responded to a question earlier Monday about reports that Iranian negotiators were considering ending talks with Washington and “completely blocking” the Strait of Hormuz in response to Israel’s military action targeting the Iran-backed Hezbollah group in Lebanon.

Asked if Iranian officials had informed him that they would no longer continue negotiations, Trump said: “No, they did not.”
