Waltine "Walt" Nauta, a personal aide to Trump, was indicted in Smith's investigation into Trump's alleged mishandling of classified documents.

Nauta, Trump's former White House military valet and a Navy veteran, came under scrutiny for his conflicting narratives on whether he moved boxes of documents at the former president’s Mar-a-Lago estate in Florida at Trump's urging.

Numerous former Trump staffers were quoted by The Washington Post as saying that Nauta was always by Trump's side and followed the former president to his Mar-a-Lago residence where the classified documents were eventually seized, even after many left Trump for other jobs.

Nauta’s military background dates back to 2001, and he served across the United States before retiring as a senior chief culinary specialist, according to records obtained from the Navy.

He was charged Friday with one count of making false statements and representations, which carries a sentence of up to five years.

The special counsel overseeing the Justice Department's investigation into Trump's handling of classified documents will make a statement at 3 p.m. ET, according to the department.

Smith will not take questions. The statement will be live-streamed on the department's website.

The indictment returned by a federal grand jury in Florida in the Trump classified documents case overseen by Smith has been unsealed.

The federal grand jury indicted Trump on seven criminal charges related to his alleged mishandling of more than 100 classified documents discovered last year at his Mar-a-Lago resort in Florida, NBC News reported yesterday.

The former president shared last night that he had been indicted. One of his lawyers, Jim Trusty, said on CNN shortly afterward that the legal team had received a summons. The language in the summons laid out some of the charges, Trusty said, and asked that Trump appear at a courthouse in Miami on Tuesday at 3 p.m. ET. (Trump said today that Trusty is no longer representing him.)

Trump's arraignment Tuesday will be overseen by either Magistrate Judge John Goodman or Chief Magistrate Judge Edwin Torres, a court official told NBC News.

U.S. District Judge Aileen Cannon was assigned to oversee the trial and was chosen randomly, the official said.

The hearing is expected to take place in a new Miami courthouse and Trump will likely enter through an underground parking lot, according to the court official.

Journalists are expected to be able to use approved electronic devices but will be prohibited from texting during court proceedings.

The venue for Trump's trial is still undecided.

Biden was asked at an event in North Carolina about Trump's indictment. He gave a one-sentence answer: "I have no comment at all."

Former Secretary of State Mike Pompeo said yesterday in a Fox Business interview that those with access to classified documents "have a responsibility to handle them appropriately, and those of us who don’t have to be held accountable for that, no matter which party they’re from."

Pompeo, who decided not to run against his former boss for the GOP presidential nomination, said, "When you make a mistake, you need to own it," adding, "I hope that everyone who takes this sacred duty of protecting this information will do that.”

Hillary Clinton, who ran for president against Trump in 2016, is selling "limited edition But Her Emails" hats "in light of recent news," the former secretary of state said in an Instagram post this morning.

Her announcement comes as Trump's criticisms of then-candidate Clinton resurface. In 2016, Trump vowed to "enforce all laws concerning the protection of classified information" as president. Drawing a contrast between himself and Clinton, who the State Department said had violated federal records rules by using a private email server while secretary of state, Trump added that "no one will be above the law."

Trump made the remarks while addressing supporters at a rally in North Carolina, and the clip appeared in much of this morning's news coverage of the indictment, including in The Guardian, CNN, and The New York Times.

Former Vice President Mike Pence said at a campaign stop in New Hampshire today that he's "deeply troubled" by the indictment against Trump, saying "it would only further divide our nation at a time when American families are facing real hardship at home and real peril abroad."

Pence, who like his former boss is vying for GOP presidential nomination, said he was also concerned about "the message this sends the wider world," adding, "We're the beacon of democracy, but we're also an emblem of justice in the world."

U.S. leaders and those aspiring to lead should remember "no one is above the law," and "the handling of classified materials of the United States is a serious matter," he said.

Pence encouraged New Hampshire voters "to pray for our former president and his family," saying the "unprecedented indictment" marks "a sad day in America."

Sen. John Barrasso, R-Wyo., is the first GOP leader in the Senate to weigh in on Trump's indictment. Aligning with many other Republican colleagues, he called the indictment an "unequal application of justice."

Much of his statement shifted focus toward Biden's own classified documents probe and, a popular Republican talking point, former Secretary of State Hillary Clinton's emails.

"We are learning more and more about the ethical mess President Biden and his family were involved in. no indictments," Barrasso wrote. "You can't help but ask why this is happening. It feels political, and it's rotten."
