President Donald Trump spent part of his Monday trolling Tucker Carlson after the former Fox News host questioned the president’s handling of Iran and conflict in the Middle East.

Last week in a newsletter, Carlson accused Trump of being “complicit” in Israel’s strikes against Iran that sparked the current days-long exchange between the two Middle Eastern powers. The newsletter arrived in the inboxes of Carlson’s readers under the headline: “This Could Be the Final Newsletter Before All-Out War.”

“Earlier this week, unnamed Washington sources expressed concern over Israel’s ability to fend off Iran’s retaliation, which would inevitably lead to Benjamin Netanyahu ordering the American military to step in and fight on his country’s behalf,” Carlson wrote. “On Thursday, Iran’s president threatened to ‘destroy’ any country that eliminates his government’s nuclear facilities. Now, the world will learn what that looks like.”

Trump responded to Carlson’s criticisms while attending the Group of Seven Summit in Canada.

“Somebody please explain to kooky Tucker Carlson that, ‘IRAN CAN NOT HAVE A NUCLEAR WEAPON!’” Trump posted on Truth Social on Monday evening.

Earlier in the day, Trump dismissed a question from a reporter on Carlson’s concerns.

“I don’t know what Tucker Carlson is saying. Let him go get a television network and say it so that people listen,” said Trump, appearing to jab at Carlson over his exit from Fox News. Carlson now runs his own media business, the Tucker Carlson Network, and hosts a popular interview podcast.

Trump’s support for Israel and his Middle East policy appears to have alienated Carlson, as well as other isolationist-minded supporters. The comic Dave Smith recently called for Trump’s impeachment over the president’s handling of Iran.

“I supported him this last year. I apologize for doing so. It was a bad calculation. At the time, it seemed like the right one, but he should be impeached and removed for this one,” Smith said on a recent episode of “Breaking Points.” “All of his supporters should turn on him. It’s the absolute betrayal of everything that he ran and campaigned on and everything that he stood for.”

President Donald Trump plans to leave an economic summit of world leaders early because of the conflict in the Middle East.

White House Press Secretary Karoline Leavitt said in a post on X Monday that Trump had planned to stay at the economic summit longer, but will return to Washington Monday night “because of what’s going on in the Middle East.” Trump left Washington for Canada this week to meet with world leaders at the Group of Seven Summit.

“President Trump had a great day at the G7, even signing a major trade deal with the United Kingdom and Prime Minister Keir Starmer. Much was accomplished, but because of what’s going on in the Middle East, President Trump will be leaving tonight after dinner with Heads of State,” said Leavitt.

The change in the president’s plans came as he posted a warning to residents in Tehran to leave the city immediately. The Iranian capital has been bombarded for days by Israel in targeted strikes on military and other key locations.

“Iran should have signed the ‘deal’ I told them to sign,” said Trump on Truth Social. “What a shame, and waste of human life. Simply stated, IRAN CAN NOT HAVE A NUCLEAR WEAPON. I said it over and over again! Everyone should immediately evacuate Tehran!”

Earlier Monday, the president confirmed that Iran has reached out through intermediaries to negotiate to end the conflict.

“They’d like to talk, but they should have done that before,” the president told reporters at the summit. “I had 60 days, and they had 60 days. On the 61st day, I said, ‘We don’t have a deal.’ They have to make a deal, and it’s painful for both parties. But I’d say Iran is not winning this war, and they should talk, and they should talk immediately, before it’s too late.”

While at the summit, world leaders were floated a draft of a joint statement on the Israel-Iran conflict that, among other stances, would have pushed both sides to negotiate and end to the conflict. Trump reportedly refused to sign on to the joint statement.
