Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

In an interview that aired on "60 Minutes" on Sunday, former Republican Leader Mitch McConnell was openly critical of recent decisions by President Donald Trump and said he planned to be more outspoken about their differences of opinion now that he was no longer in a leadership role in the Senate.

McConnell sharply criticized the president imposing tariffs, especially on allied countries.

"It'll drive the cost of everything up. In other words, it'll be paid for by American consumers. I mean why would you want to get in a fight with your allies over this?" McConnell questioned.

McConnell often found himself at odds with Trump during his first term in the White House, he said, but claimed their relationship was all but severed after Jan. 6, 2021.

The former Senate leader reacted to Trump's sweeping pardons for the convicted rioters, saying, "I think pardoning people who have been convicted is a mistake."

President Donald Trump plans to speak with Canadian Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum on Monday morning, he told to reporters during a stopover at Joint Base Andrews on Sunday evening.

The calls are scheduled two days after he imposed 25% tariffs on both of the United States' neighboring countries.

Sheinbaum is also expected to deliver Mexico’s response to the tariffs in the morning, according to sources familiar with the situation.

The Treasury Department has given Elon Musk and representatives of his Department of Government Efficiency (DOGE) team access to the vast federal payment system responsible for handling trillions of dollars in government expenditures, multiple sources familiar with the matter said.

The payment system -- which is essentially a checkbook for the entire federal government -- is a closely held operation run by career officials, with a limited number of people authorized to access the information given it, contains sensitive information about hundreds of millions of Americans.

If Musk or his team were to attempt to block these payments, it would likely face legal challenges given the money is approved by Congress.

Sources tell ABC News that if Musk or his representatives were to request that changes be made to the system, such requests would be subject to an internal review process by Treasury Department officials.

Sen. Ron Wyden, the ranking Democrat on the Senate Finance Committee, said in a letter to Treasury Secretary Scott Bessent that any "politically-motivated meddling" in the payment systems "risks severe damage to our country and the economy."

President Donald Trump spoke to reporters on Sunday night and, among a roster of topics, mentioned that he believes his head of the new Department of Government Efficiency, Elon Musk, is doing a "good job."

At the same time, he implied that there were some things that he and Musk did not always agree on.

“I do, I think Elon is doing a good job. He's a big cost-cutter. Sometimes we won't agree with it. It will not go where he wants to go, but I think he's doing a great job. He's a smart guy, very smart, and he's very much into cutting our the budget of our federal government,” Trump said in a conversation that took place during a stopover at Joint Base Andrews.

When asked specifically about the ongoing turmoil at the U.S. Agency for International Development, where DOGE officials were reportedly taking offices as existing personnel were placed on leave, Trump said the organization has been run by “radical lunatics,” and they’re getting them out -- and that’s when he’ll make a decision about the organization.
