Three weeks after former President Donald J. Trump was indicted on costs of illegally retaining nationwide safety information and obstructing the federal government’s efforts to reclaim them, a federal grand jury in Miami continues to be investigating features of the case, in line with folks aware of the matter.

In latest days, the grand jury has issued subpoenas to a handful of people who find themselves linked to the inquiry, these aware of it mentioned. While it stays unclear who obtained the subpoenas and the type of data prosecutors had been in search of to acquire, it’s clear that the grand jury has stayed lively and that investigators are digging even after a 38-count indictment was issued this month in opposition to Mr. Trump and a co-defendant, Walt Nauta, one in every of his private aides.

Prosecutors typically proceed investigating strands of a prison case after costs have been introduced, and generally their efforts go nowhere. But post-indictment investigations may end up in further costs in opposition to individuals who have already been accused of crimes within the case. The investigations will also be used to convey costs in opposition to new defendants.

When the workplace of the particular counsel Jack Smith filed the fees in opposition to Mr. Trump and Mr. Nauta within the Southern District of Florida, the 49-page indictment provided an unusually detailed image of the previous president holding on to 31 extremely delicate authorities paperwork at Mar-a-Lago, his non-public membership and residence in West Palm Beach, Fla. Among the paperwork had been some that involved U.S. nuclear applications and others that detailed the nation’s potential vulnerabilities to assault.

The indictment was strewn with vivid images of presidency information saved in packing containers all through Mar-a-Lago in a haphazard method. Some of the packing containers had been piled up in a storage room, others in a toilet and on a ballroom stage.

Several of Mr. Trump’s aides and advisers appeared within the indictment, recognized solely as Trump Employee 1 or related descriptions. In one episode, the indictment recounted how Mr. Trump displayed a categorised map to somebody described as “a representative of his political action committee” throughout a gathering in August or September 2021 at his golf membership in Bedminster, N.J.

The consultant of the PAC was Susie Wiles, one of many high advisers for Mr. Trump’s presidential marketing campaign, in line with two folks briefed on the matter. A Trump spokesman declined to remark.

Ms. Wiles’s look within the indictment was reported earlier by ABC News.

The proven fact that Ms. Wiles might grow to be a prosecution witness ought to Mr. Trump’s case go to trial, at the same time as she helps run his third bid for workplace, underscores the complexities that the previous president now faces as he offers with each a presidential marketing campaign and a prison protection with an overlapping solid of characters.

During the assembly with Ms. Wiles, the indictment says, Mr. Trump commented that “an ongoing military operation” in an unnamed nation was not going effectively. He then confirmed Ms. Wiles, who didn’t have correct safety clearance, a categorised map of that nation, the indictment says, even whereas acknowledging that he shouldn’t be displaying the map and warning Ms. Wiles “to not get too close.”

Many of Mr. Trump’s aides and employees at Mar-a-Lago were questioned as a part of the investigation that resulted in his indictment, and Mr. Trump has been barred from discussing the details of the case with them although many work in shut contact with him. Mr. Trump has made defending himself in opposition to the fees a central a part of his political and fund-raising messages, including to the extent of overlap that exists between his authorized and political worlds.

Other aides who’ve been near Mr. Trump are featured within the indictment, similar to “Trump Employee 2,” who has been recognized as Molly Michael, an assistant to Mr. Trump within the White House and his post-presidential workplace. The portion of the indictment describing the transcript of an audio recording during which Mr. Trump described what he mentioned was a plan to assault Iran given to him by the Pentagon lists somebody as a “staffer,” whom three folks recognized as Liz Harrington, a spokeswoman for Mr. Trump.

Some Trump aides and workers who had initially caught the eye of investigators had been talked about within the indictment solely in passing.

At one level, for instance, prosecutors beneath Mr. Smith gave the impression to be targeted on Mr. Nauta’s dealings with a upkeep employee at Mar-a-Lago, Carlos Deoliveira, who helped him transfer packing containers right into a storage room on the compound. The motion of these packing containers — at Mr. Trump’s request, prosecutors say — finally lay on the coronary heart of a conspiracy cost within the indictment accusing Mr. Trump and Mr. Nauta of obstructing the federal government’s try to retrieve all the categorised supplies in Mr. Trump’s possession.

In a beforehand unreported element, prosecutors obtained a warrant to grab Mr. Deoliveira’s cellphone as a part of their investigation, in line with an individual aware of the matter.

Records from the cellphone finally confirmed that Mr. Deoliveira known as an I.T. specialist who labored for Mar-a-Lago final summer time across the time that prosecutors issued a subpoena to Mr. Trump’s firm, the Trump Organization, demanding footage from a surveillance digital camera close to the storage room the place the packing containers of paperwork had been saved.

But Mr. Deoliveira is referenced as “an employee of the Mar-a-Lago Club” in solely a single paragraph within the indictment.
