The source is a Trump employee who told federal agents about moving boxes of documents at Mar-a-Lago at the former president’s direction, according to The Washington Post. The witness account is reportedly accompanied with security-camera footage, according to anonymous sources.

“Day by day the evidence that proves Trump personally orchestrated the theft and concealment of top secret documents becomes stronger,” tweeted Harvard law professor and legal scholar Laurence Tribe. “Any shadow of a doubt about his guilt is rapidly vanishing.”

Tribe told Newsweek via email that if the report is accurate from the standpoint of visual evidence, “it removes any reasonable doubt that the concealment of classified documents that the former president knew were being sought by the government took place with his knowledge and at his personal direction.”

“Beyond that, Trump’s repeated insistence that the documents belonged to him erases any possibility that he was merely trying to secure them to protect national security,” Tribe said. “Even when he was president, that insistence would have been damning because our system of government sets its face against any leader’s claims to be the State.

“But because Trump was no longer president when he directed this obvious obstruction of the government’s efforts to retrieve and secure the sensitive documents that belonged to the nation as a whole, prosecuting him becomes all the more imperative,” he added.

Trump spokesman Taylor Budowich reportedly declined to answer The Washington Post’s detailed questions, instead blaming the Biden administration for weaponizing law enforcement and fabricating a “document hoax in a desperate attempt to retain political power.”

“Every other President has been given time and deference regarding the administration of documents, as the President has the ultimate authority to categorize records, and what materials should be classified,” Budowich said.

He also accused the DOJ of a “continued effort to leak misleading and false information to partisan allies in the fake news.”

Sources told The Washington Post that a witness story changed dramatically in regards to the handling of sensitive documents or boxes that may have contained such documents.

The witness reportedly denied the allegations in their first interview, and then changed their story “dramatically” in a second interview conducted after federal agents had gathered more evidence.

It was during that second interview that the witness allegedly described moving boxes at Trump’s request.

Ryan Goodman, former special counsel for the Department of Defense and a professor at the New York University School of Law, tweeted that the DOJ has an “astonishing level of evidence. That would convince jurors.”

On MSNBC’s Morning Joe on Thursday, attorney George Conway compared Trump’s actions to that of a mob boss.

“It’s like the U.S. attorney trying to bring a big mob case…and all of a sudden they get the call from NYPD saying, ‘Hey, the big boss, the capo, is loading jewelry on a truck at Kennedy Airport,’” Conway said.

The DOJ’s filing in response to Trump’s request for the Supreme Court to intervene in the matter has been applauded by legal experts, including former appellate defender Teri Kanefield.

She tweeted that two particular words—“developed evidence”—were an important part of the filing because it could contradict Trump’s previous statements while also driving the former president “crazy [for] not knowing who the rat is.”

The DOJ investigation continues as the ninth and potentially final January 6 committee hearing will take place Thursday evening. Trump’s “state of mind” that day, in addition to his role in encouraging his supporters to storm the Capitol, is expected to be part of the presentation.

Newsweek reached out to the DOJ, Trump and Goodman for comment.
