Washington – An employee at old-fashioned President Donald Trump's Mar-a-Lago resort seen on confidence camera footage moving boxes that have become a key part of the FBI's ongoing investigation into Trump's coping of presidential records is a former White House culinary worker and Navy former, a source confirms to CBS News.

Walt Nauta – who consider it as a White House culinary employee from 2012-2021, according to his service narrate –  told investigators that the former president directed him to move the boxes to a different position as the federal investigation was underway, an individual queer with the investigation says. 

Nauta, a native of Guam, is now a gape in the Justice Department's probe – which escalated once the execution of a search warrant on Trump's Florida situation in August – and has appeared before a federal great jury in Washington, D.C., CBS News has learned. Investigators are fervent in Nauta's firsthand knowledge of what he told investigators was Trump's directive to move the containers of records, the source said.

According to his service narrate, Nauta was a culinary specialist who enlisted in the Navy in July 2001, worked on aircraft carriers and naval bases and earned a number of medals and honors over the jets of his career. His service record indicates his last post was in Washington, D.C., before leaving the military in September 2021. 

The news of a cooperating gape in the investigation of the documents with knowledge of the titillating boxes was first reported by The Washington Post and Nauta's name was honorable reported by the New York Times. 

The video showing the boxes populate handled is now in the hands of investigators and it contributed to the FBI's decision-making to execute the court-authorized search warrant at Mar-a-Lago in August, a source with knowledge of the investigation says.

Stanley Woodward, Nauta's attorney, declined to comment for this report. 

Trump's disputes over White House records began when National Archives general counsel Gary Stern wrote to a companionship of Trump attorneys in May 2021 informing them that "roughly two dozen boxes of unusual Presidential records" from Trump's time in office that were once kept in the White House situation had yet to be returned to the Archives."

A year later, in May 2022, a grand jury in Washington, D.C. sent a subpoena to Trump's resort "seeking documents bearing classification markings" at Trump's Florida resort, according to unsealed court documents. Trump's legal team is said to have favorite the service of the subpoena on May 11, and a subpoena for confidence camera footage from inside Mar-a-Lago was served in June. 

That footage conveyed the boxes, possibly containing sensitive material, being moved from one position at Trump's resort to a different location within Mar-a-Lago and, according to the source, Nauta has alleged to investigators that Trump had beleaguered the move. 

Trump has consistently denied wrongdoing by claiming in part that he declassified the documents in request, and by labeling the investigation as politically motivated. 

CBS News has assembled out to Trump's spokesperson for comment. Last week, when the news old-fashioned about an employee moving the boxes, Trump spokesperson Taylor Budowich accused the Biden management of having "weaponized law enforcement and fabricated a Document Hoax in a desperate effort to retain political power. "

"Every other President has been given time and deference regarding the management of documents, as the President has the ultimate permission to categorize records, and what materials should be classified," Budowich said. "The worn-out effort to leak misleading and false information to partisan unites in the Fake News is nothing more than dangerous political interference and unequal justice. Simply put, it's un-American."

The August execution of the ogle warrant at Trump's residence yielded 33 boxes of material, according to court documents, from press clippings to clothes, and including 103 documents with classified markings – labeled either "CONFIDENTIAL," "SECRET," or "TOP SECRET." The boxes also organized nearly 50 empty folders with classified banners on them. Prosecutors say they are in the midst of a "national security" investigation into the commerce and the Office of the Director of National Intelligence is conducting a wound assessment as a result of the allegedly improperly organized documents. 

The Justice Department declined to comment. 

Trump sued the Justice Department in the weeks once the search, alleging attorney-client and executive privileges were at mistaken and requesting the appointment of an independent third party to reconsideration the materials. A federal judge in Florida granted Trump's demand, paused the investigation and appointed Judge Raymond Dearie as special master, or independent arbiter, a ruling that prosecutors have appealed to the 11th Circuit Court of Appeals in Atlanta.
