Trump 2nd term live updates: Trump defends tariffs, declines to comment on Ukraine aid

National Security Advisor Mike Waltz said President Donald Trump and his national security team will have a "broad discussion of what's next" for Ukraine when they meet Monday, following Friday's explosive Oval Office meeting with Ukrainian President Volodymyr Zelenskyy.

Waltz expressed support for European efforts to negotiate peace, saying "we welcome the Europeans taking a lead on European security."

Waltz told Fox News the Trump administration wants Zelenskyy to express "regret" for the volatile meeting.

"What we need to hear from President Zelensky is that he has regret for what happened, he's ready to sign this mineral deal, and that he's ready to engage in peace talks. I don't think that's too much to ask," Waltz said.

Waltz also said the administration expects both sides to make concessions, broadly outlining what that might look like.

"I think a lot of people can see what those roughly will be; in terms of security guarantee for some type of territorial concessions, those broad outlines are evident," he said. "Does both sides have the will to sit down and drive this towards peace? That's President Trump's objective. That's what he was elected to do, and that's what we're ready to do and trying to do right now."

Elon Musk's Department of Government Efficiency updated its website overnight with new figures, now claiming to have saved $105 billion. However, the figure remains unverifiable and the site claims to have posted only 30% of the receipts supporting this total.

According to the website, all "contract, grant, and lease cancellations" posted account for just 30% of the claimed total savings.

"We are working to upload all of our receipts in a digestible and transparent manner consistent with applicable rules and regulations," the website states. It also claims to have saved $652.17 per taxpayer.

The Senate is expected to vote on Monday afternoon to confirm Linda McMahon as the secretary of the Department of Education.

After months of anticipation, President Donald Trump could soon sign an executive order that directs the education secretary to spearhead the closing of the federal agency.

As previously reported by ABC News, sources say the order will call for McMahon to submit a proposal to diminish the agency and direct Congress to pass legislation that gets rid of it. However, Trump's directive will be illegal without congressional approval, according to experts. Any proposed legislation would likely fail without 60 Senate votes.
