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

President Donald Trump is participating in a Women's History Month Event at the White House at 3 p.m. ET on Wednesday.

At 1 p.m. ET, White House press secretary Karoline Leavitt will hold a briefing, where she's expected to be peppered with questions on the Signal group chat involving top officials discussing a U.S. attack on Houthis in Yemen -- a message chain that came to light after a journalist was inadvertently added.

Election experts tonight are sounding the alarm Tuesday evening about President Donald Trump's executive order on election rules, with one calling it "an illegal power grab that would block tens of millions from voting."

Wendy Weiser, the vice president for democracy at the nonprofit Brennan Center, took issue with ID requirements to register to vote laid out in the order, as well as threats to revoke funding from states that don't comply.

Sam Tarazi, the co-founder of the nonpartisan Voting Rights Lab, said the order was sure to face legal challenges in court. “President Trump’s executive order is more than a direct affront to our Constitution and the checks and balances that have secured our elections for generations," she said.

Among other statements, the order claims the U.S. "has not adequately enforced Federal election requirements that…prohibit non-citizens from registering to vote."

But recent audits -- including in Republican states -- have shown that noncitizen voting is extremely rare.

In Georgia, for example, an audit of the state's voter rolls last year found just 20 noncitizens out of 8 million registered voters. A similar audit of Iowa's 2.3 million voters revealed 87 instances where individuals cast ballots and later self-reported as noncitizens.

Some election officials are praising Trump's move. That includes Georgia Secretary of State Brad Raffensperger, a Republican who once feuded with Trump over false claims of election fraud.

“Thank you, President Trump, for this executive order ensuring that only American citizens decide American elections," Raffensperger said in a statement. "This is a great first step for election integrity reform nationwide."

Elon Musk and his Department of Government Efficiency team are reviewing how The Atlantic editor was added to a Signal group chat where plans for a U.S. military attack in Yemen were discussed, a senior White House official confirmed to ABC News.

In his interview with Fox News Tuesday night, National Security Adviser Mike Waltz alluded to Musk's involvement, saying, "I just talked to Elon on the way here -- we have the best technical minds looking at how this happened."

The White House official confirmed to ABC News that DOGE is involved and that the team is working with other teams to make communications "more secure and efficient."

Additionally, White House press secretary Karoline Leavitt said on Fox News Tuesday evening that "Elon Musk's team of experts is looking at this, and the National Security Council is all digging into this matter to ensure this could never happen again."

During an appearance on Fox News on Tuesday, National Security Adviser Mike Waltz seemed to accuse The Atlantic's Jeffrey Goldberg of somehow putting his contact incorrectly into Waltz's phone or getting into the Signal group chat in another way.

This comes after several top members of President Donald Trump's administration discussed a military operation in Yemen in a group chat that included Goldberg.

Waltz seemed to imply that it was an error with the contact on his phone, saying, "Have you ever had somebody's contact that shows their name and then you have and then you have somebody else's number..." he said when asked how Goldberg's contact was in his phone.

"You got somebody else's number on someone else's contact. So, of course, I didn't see this loser in the group. It looked like someone else. Now, whether he did it deliberately or it happened in some other technical mean, is something we're trying to figure out," Waltz added.

The Atlantic reported on Monday that the user was called "Michael Waltz" who invited Goldberg into the chat. Waltz insisted that he does not know or speak to Goldberg.

Waltz did concede that he did indeed put the chat together and bears responsibility for that.

"I take responsibility. I built the group. Okay, so, but look, that's the part that we have to figure out, and that's the part that was embarrassing, yes," Waltz said.
