The Justice Department has given critics a new reason to believe the agency has become politicized in an unprecedented way since Joe Biden took office as president after a court filing on Thursday.

As reported by the UK’s Daily Mail, the DOJ mistakenly “disclosed a list of Donald Trump documents being vetted by ‘privilege review teams’ that were included among thousands of materials seized from Mar-a-Lago.” Included in the exposed documents, “which Trump’s lawyers are trying to keep out of the hands of government investigators, includes discussions about presidential pardons late in Trump’s term – including the pardon of former Illinois Gov. Rod Blagojovich.”

The documents had been ordered sealed by a federal judge, but they were nevertheless published on government court docket. However, the documents have since been taken offline. Nevertheless, the ‘error’ is likely to fuel new speculation that Biden’s Justice Department is politically biased against the former president.
