Walt Nauta, an aide to former president Donald Trump, pleaded not guilty on Thursday in a Miami federal court to several counts of mishandling classified material and conspiracy to obstruct justice following Special Counsel Jack Smith’s indictment last month.

Nauta arrived at the courthouse a little after 10 a.m. for the brief hearing that lasted only a couple of minutes, according to media reports. He left a little more than an hour later and did not speak to reporters.

Nauta was present when Trump appeared in court on June 13 and pleaded not guilty to 37 federal counts, including over two dozen violations of the Espionage Act. Nauta, who is facing six charges as part of the classified documents probe, was not arraigned at the time due to lack of legal representation.

He is now being represented by Sasha Dadan, a Republican criminal defense attorney from Fort Pierce, about two hours north of Miami, according to media reports.

A Navy veteran, Nauta served as a valet – a personal assistant or butler — while Trump was in office. In September 2021, he left the military to work as a personal aide to Trump at Mar-a-Lago. His salary was paid by Save America, a Trump political action committee, where he made $135,000 in 2022, according to the Washington Post.

Senior Trump aides have described Nauta in the media as a “very sheepish” person who “asks permission for everything,” but was was “willing to do whatever” for Trump.

On Wednesday, federal judge Bruce Reinhart, unsealed sections of the affidavit the FBI submitted in 2022 to obtain a search warrant of Mar-a-Lago in its hunt for classified documents.

Surveillance footage showed Nauta moving several boxes from a storage room days before prosecutors arrived to take possession of them. Alongside the footage are images showing dozens of boxes in the same location. “The current location of the boxes removed from the storage room but not returned to it is unknown,” the affidavit said.

A source told the Washington Post that Nauta initially denied moving the boxes of documents during an interview with the FBI, but later said Trump told him to move the boxes during a second interview.

“I have just learned that the ‘Thugs’ from the Department of Injustice will be Indicting a wonderful man, Walt Nauta, a member of the U.S. Navy, who served proudly with me in the White House, retired as Senior Chief, and then transitioned into private life as a personal aide. He has done a fantastic job!” Trump wrote on Truth Social, his social media platform, in early June following the news of the indictment.

“They are trying to destroy his life, like the lives of so many others, hoping that he will say bad things about ‘Trump,’” Trump said of Nauta. “He is strong, brave, and a Great Patriot. The FBI and DOJ are CORRUPT!”

Nauta’s legal bills are being paid by a Trump political organization, according to NBC News.
