According to US media, a Donald Trump personal aide has been charged with mishandling secret documents.
Veteran of the navy and White House aide Walt Nauta later worked at Mr. Trump's Mar-a-Lago resort.
What accusations Mr. Nauta is up against in this case are currently unknown.
According to his attorneys, Mr. Trump is accused of mishandling classified documents and obstructing the justice system on seven counts.
The Wall Street Journal was the first publication to report on Mr. Nauta's accusations.
The newspaper claims that Mr. Nauta was the subject of the investigation after video surveillance captured him removing boxes from a storage area. It was captured both before and after Mr. Trump was served with a subpoena in May demanding the return of official records kept at his Mar-a-Lago estate in Florida.
Before declining further questioning, Mr. Naura spoke with investigators at least twice, according to the Journal.
Asserting that the US Justice Department was "trying to destroy" Mr. Nauta's life "like the lives of so many others, hoping that he will say bad things about Trump," Mr. Trump made this claim on his social media platform Truth Social.
Mr. Trump continued, "He is strong, brave, and a great patriot.".
The attorney for Mr. Nauta has been contacted by the BBC for comment.
The charges against Mr. Nauta and Mr. Trump have not yet been released by the court. On June 13, the charges against Mr. Trump will be read in a Miami, Florida, federal courtroom.
The former president is accused of mishandling classified documents and obstructing efforts to look into how the documents were stored at his Florida home, according to the former president's attorneys on Thursday. Both of these are federal felonies that are punishable by imprisonment.
A few hours later on Friday, Jim Trusty and John Rowley, Mr. Trump's attorneys, announced that they would no longer be representing him.
On Truth Social, Mr. Trump acknowledged the restructuring of his legal team.
The two said in a statement that they had "tendered our resignations as counsel to President Trump this morning and we will no longer represent him on either the indicted case or the 6 January investigation.".
Both of them acknowledged that it had been "an honor" to spend the previous year defending Mr. Trump, but added that given that the lawsuit had been filed in Miami, the attorneys felt it was now a "logical moment" to withdraw.
According to law enforcement officials speaking to CBS, the US partner of the BBC, Mr. Trump's team will meet with the US Secret Service on Friday to arrange his travel and court appearance.
