Takeaways from the historic Justice Department court filing on the Mar-a-Lago search

(CNN)- Former President Donald Trump has pushed an "incomplete and inaccurate narrative" in his recent court filings about the Mar-a-Lago search, the Justice Department said in a historic court filing late Tuesday night.

Prosecutors fleshed out new details about the ongoing criminal investigation into Trump's potential mishandling of classified documents, which he took from the White House to his resort and home in Florida. Trump and his allies have denied any wrongdoing.

In total, the US government has recovered more than 320 classified documents from Mar-a-Lago since January, including more than 100 seized in the August search, DOJ says.

The filing is in response to Trump's bid for a "special master" in a civil lawsuit against the Justice Department, weeks after the FBI searched Mar-a-Lago. The judge handling the case, a Trump appointee, has said her "preliminary intent" is to bring in a special master. A hearing is scheduled for Thursday.

Here are some key takeaways from the filing, what we learned and where we go from here.

Docs were moved and possibly hidden from investigators

Documents were "likely concealed and removed" from a storage room at Mar-a-Lago as part of an effort to "obstruct" the FBI's investigation, the Justice Department said in its filing Tuesday.

What's more, the DOJ said that the search "cast serious doubt" on his lawyers' claims that there had been a "diligent search" to return classified material in response to a grand jury subpoena.

A Trump lawyer signed a statement to the Justice Department in June attesting that all of the classified material at Mar-a-Lago had been returned.

"That the FBI, in a matter of hours, recovered twice as many documents with classification markings as the 'diligent search' that the former President's counsel and other representatives had weeks to perform calls into serious question the representations made in the June 3 certification and casts doubt on the extent of cooperation in this matter," DOJ wrote.
