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

First lady Melania Trump made her first public remarks of Trump's second administration Monday afternoon, hosting a roundtable in support of the "Take It Down" Act which is intended to criminalize the publication of deepfake and non-consensual pornography and require platforms to remove such content.

"It's heartbreaking to witness young teens, especially girls, grappling with the overwhelming challenges imposed by malicious online content, like deep fakes," Trump said.

Trump called attention to a 15-year-old victim of fake non-consensual images who was present at the roundtable, among other victim advocates.

In imploring Congress to prioritize this Act -- which has passed the Senate but not the House -- the first lady also made a point to call out Democrats.

"I must admit, however, I expected to see more Democrat leaders with us here today to address this serious issue," she said. "Surely as adults, we can prioritize America's children ahead of partisan politics."

Trump was joined by Sen. Ted Cruz, R-Texas, who is a sponsor of the bill and delivered opening remarks, saying there is "no more important issue for our first lady to lean on than protecting children online."

Speaker of the House Mike Johnson was also present.

Elon Musk will be in the chamber Tuesday evening for President Donald Trump's address, ABC News has confirmed.

After President Donald Trump signed an executive order making English the official language of the U.S., an Alabama Republican has proposed a bill to ensure the policy becomes permanent federal law.

Rep. Robert Aderholt introduced the bill, "Designation of English as the Official Language of the United States Act of 2025," on Monday.

The bill seeks to establish a uniform English language rule for naturalization and provide clarity in the interpretation of U.S. laws, according to Aderholt.

"America has always been a melting pot of cultures, traditions, and languages," Aderholt wrote in a statement. "However, throughout our history, English has remained the common thread uniting us as one nation. By designating English as the official language of the United States, we are reinforcing our commitment to a shared national identity and ensuring clear and effective communication across all levels of government."

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."
