Trump says 3rd term isn't a joke, despite term limit

The Canadian prime minister's office has released a statement following the phone call between President Donald Trump and Prime Minister Mark Carney, calling it a "very constructive conversation about the relationship between our two countries."

"The leaders agreed to begin comprehensive negotiations about a new economic and security relationship immediately following the election," the statement read. Trump also said he planned to meet with the prime minister after Canada's elections next month.

In the meantime, the prime minister's office said talks between their officials and U.S. Commerce Secretary Howard Lutnick will "intensify to address immediate concerns."

Carney also informed Trump "his government will implement retaliatory tariffs to protect Canadian workers and our economy, following the announcement of additional U.S. trade actions on April 2."

Vice President JD Vance and second lady Usha Vance arrived in Greenland for a scaled-back trip after backlash to their visit, which originally was set to include cultural events but now is focused on a stop at the U.S. military's Pituffik Space Base.

They briefly greeted service members stationed there as they ate lunch. Vance noted he was the first vice president to visit Greenland, saying it was "a pretty cool thing," before giving an overview of their visit.

"We're talk to the command and some of the Guardians about what exactly the base does and all the important ways it contributes to national security. We're going to get a briefing, of course, about, you know, what you guys do every day," Vance said.

"And then we're going to talk just about, as you've heard, we have some interest in Greenland from the Trump administration, so we're going to talk a little bit about that with our friends in the media," Vance added.

The Trump administration moved to officially dissolve the U.S. Agency for International Development, according to a memo distributed to agency employees on Friday.

Jeremy Lewin, the agency's new deputy director and a former DOGE official, wrote. In a memo obtained by ABC News, Lewin said the State Department "will seek to retire USAID's independent operation" immediately and "assess" whether to rehire some unknown number of officials to "assume the responsible administration of USAID's remaining life-saving and strategic aid programming."

As part of the move, the memo continued, "all non-statutory positions at USAID will be eliminated."

"Thanks to President Trump, this misguided and fiscally irresponsible era is now over. We are reorienting our foreign assistance programs to align directly with what is best for the United States and our citizens," Secretary of State Marco Rubio said in a statement.

The State Department also said that its leadership, along with USAID leadership in place, had notified Congress of its intent to reorganize some USAID functions within the State Department by July 1.

The overall push to eliminate USAID is being challenged in multiple court cases.

Overnight, Defense Secretary Pete Hegseth had another press event in the Philippines, where he was asked if he bore any responsibility for what other government officials labeling the Signal chat a mistake.

He answered by saying his job is to deter and defeat enemies and he was proud of U.S. Central Command. He didn't apologize or call it a mistake.

"We are reestablishing deterrence, and as the leader of that department, my job is to advise and work alongside the president and then work with my fellow Cabinet members to ensure that we're operationalizing in every way possible," he said.

Later, as he was boarding a flight to Japan, a reporter asked Hegseth if he would comply with a federal judge's order to preserve the texts in the Signal chat. His response was, "I'm going to get on the plane."
