The Justice Department asked a federal appeals court to overturn a judge's appointment of an arbiter to review documents seized during an FBI search of Donald Trump's Florida estate.

The scope of the arbiter's duties has been the subject of several weeks of litigation. He was assigned by a judge to look over the records that were taken in the Mar-a-Lago search.

The investigation into the storage of top- secret documents at the home has been delayed due to the special master process. The department was able to use the seized classified documents as part of its criminal probe after the 11th Circuit lifted a temporary bar.

The move allowed a core aspect of the probe to resume, which greatly reduced the chance that the special master process would have a significant impact on the investigation. The judge who appointed the special master had no reason to do so, and Trump was not entitled to an independent review of the seized records, according to the department lawyers.

The department's brief states that there is no plausible claim of personal attorney-client privilege as to the seized government records.

They said that the special-master review process is unwarranted.
