Here are some of the latest developments in the DOJ's investigation into Donald Trump

Former President Donald Trump is at the center of an evolving investigation and many are unsure of what the future may hold. Over the last several weeks, several developments have come to light. Here are details about some of the key developments.

Peter Navarro sounding off on Federal Bureau of Investigations (FBI) agents:

"Federal prosecutors acting for the Department of Justice have given more details about the arrest of former Trump aide Peter Navarro, contradicting his account of the event and describing outlandish, combative behavior on the part of the notorious 2020 election denier," The Independent reported.

The news outlet's report has also detailed Navarro's description of his role in the failed coup attempt to have former Vice President Mike Pence (R) overturn the 2020 presidential election.

Since Navarro pled not guilty, he is now "now trying to compel the government to release more evidence to him via discovery, claiming that it has been holding back information to which he is entitled."

However, the U.S Department of Justice (DOJ) has pushed back against his claims, according to a filing by the U.S. District Court for the District of Columbia.

“While the volume of discovery might be small, its volume is not a reflection of its thoroughness,” the document reads. “Instead, it reflects the straightforward nature of this case—the Defendant received a subpoena, ignored the subpoena’s document demand, and refused to appear for testimony despite the admonition that he must.”

“And only a few days before,” the document said, “when the case agents attempted to interview him and serve him with a subpoena at his residence, the Defendant at first refused to open the door and then, when he did, told the agents to “get the f*** out of here.”

Trump staffers' focus amid the former president's White House departure:

Politico recently published a report detailing accounts from former Trump administration aides and White House officials. Many staffers were reportedly more focused on securing "jumbos" —commonly referred to as the larger portraits that wee on the West Wing walls.

The report also suggested that staffers also seemed disinterested in properly sorting through important government documents. “We were 30 days behind what a typical administration would be,” one former Trump aide admitted.

"Throughout the months of December and January, administration officials were given guidance by the White House counsel’s office on how to abide by the Presidential Records Act, the post-Watergate law that dictates the procedures and processes for preserving government documents," Politico reported.

It was also reported that "Aides said they recalled very few conversations during the transition about what to do with the documents that Trump would, on occasion, bring up to the White House residence."

Alarming storage facility footage:

FBI agents' warrant reportedly came after reviewing new Mar-a-Lago surveillance footage that captured a hallway near a storage unit where classified government documents were stored, the New York Times reported.

It was also reported that people familiar with the investigation said they "also received information from at least one witness who indicated that more material might remain at the residence."
