Walt Nauta, who worked as a military valet at the White House before relocating to Mar-a-Lago to continue working for Donald Trump, was also indicted Thursday in the Trump classified documents case. The Wall Street Journal first reported the indictment.

Nauta has long been a focus of that investigation, after he was seen on surveillance footage moving boxes from a storage room before and after investigators issued a May subpoena seeking the return of all government documents in Trump’s possession, The Wall Street Journal reported. Natua told investigators that he did so at Trump’s request.

Investigators spoke with Nauta at least twice and asked him to submit to further questioning, in part to clarify what prosecutors believed to be contradictory statements. He refused further questioning, the Journal reported, out of concerns about whether prosecutors are considering charges against him.

An attorney for Nauta declined to provide a comment on the charges to the WSJ.

Trump acknowledged the charges on Truth Social, writing:

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