Trump admin updates: ICE launches immigration enforcement operation in Boston

President Trump on Friday was asked to weigh in on Florida's surgeon general moving to end vaccine mandates in the state, including for children.

"Well, I think we have to be very careful," Trump said. "Look, you have some vaccines that are so amazing. The polio vaccine I happen to think is amazing. A lot of people think that COVID is amazing. You know, there are many people that believe strongly in that. But you have some vaccines that are so incredible, and I think you have to be very careful when you say that some people don't have to be vaccinated. It's a very tough position."

The president added, "You have vaccines that work. They just pure and simple work. They're not controversial at all. And I think those vaccines should be used, otherwise some people are going to catch it and they endanger other people. And when you don't have controversy at all, I think people should take them."

President Trump on Friday announced that next year's G20 summit will be held in Miami, Florida. Trump later said leaders will gather at his Doral golf property.

The agenda for the summit is being organized by Treasury Secretary Scott Bessent, Trump said. The annual meeting brings together world leaders to discuss economic issues.

"President Trump's America First initiative does not mean America alone. It means America leads," Bessent said in the Oval Office.

Trump said he will not be going to this year's G20 summit in South Africa. Instead, he said Vice President JD Vance will attend.

President Donald Trump on Friday signed an executive order renaming the Department of Defense to the "Department of War."

"I think it's a much more appropriate name, especially in light of where the world is right now," Trump said. "We have the strongest military in the world. We have the greatest equipment in the world. We have the greatest manufacturers of equipment by far. There's nobody to even compete."

Defense Secretary Pete Hegseth said the name change was about "restoring the warrior ethos" in the military.

The formal renaming of the department would require Congress to act, but the order is expected to say the new name can be used in official correspondence and ceremonial contexts and non-statutory documents.

Trump was asked if he thought Congress would codify the name change. "I don't know, but we're going to find out. But I'm not sure they have to," he responded.

President Donald Trump said it is "time to end the Democrat Epstein Hoax, and give the Republicans credit for the great, even legendary, job that they are doing," in a social media post Friday.

After survivors linked to the convicted sex offender Jeffrey Epstein testified to lawmakers on the Hill earlier this week, Trump is accusing Democrats of politicizing their stories.

"They knew everything there was to know about Epstein, but now, years after his death, they, out of nowhere, are seeming to show such love and heartfelt concern for his victims. Does anybody really believe that?," Trump said in the post.

Trump also claimed that the Justice Department has given Congress "everything requested of them."

However, House Oversight Chairman James Comer told ABC News' Linsey Davis earlier this week that he was anticipating a new trove of Epstein-related documents from the DOJ "any day."
