A federal judge said parts of the affidavit used to obtain a search warrant for former President Donald Trump’s home Mar-a-Lago can be unsealed, NBC News reported Thursday.

The Department of Justice originally asked U.S. Magistrate Judge Bruce Reinhart not to unseal the highly controversial document which suggests the government had probable cause to believe the search of Mar-a-Lago was justified and that it would in fact turn up evidence of illegality.

Prosecutors from the Justice Department’s National Security Division said they opposed the release of the affidavit “to protect the integrity of an ongoing law enforcement investigation that implicates national security.”

Judge Reinhart said Thursday he was “not prepared to find the affidavit should be fully sealed,” during a court hearing between members of the media and the Justice Department.

“There are portions of it that could, at least, presumptively be unsealed.”

Media organizations including The New York Times, CBS News and others asked the court to unseal the affidavit, arguing the affidavit’s release would help the public determine if the Justice Department had legitimate reasons for the search. Trump, too, has called for the release of the unredacted affidavit, though his lawyers have not been entered as interested parties in the court proceedings.

The judge gave prosecutors one week to file their proposed redactions to the affidavit – which likely contains a more detailed accounting of the reasons behind last week’s Mar-a-Lago search — and said he will make a decision after that, according to CBSNews.com.
