Constitutional legal scholar Laurence Tribe is charging that federal statute mandates that Donald Trump-appointed U.S. District Court Judge Aileen Cannon recuse herself from presiding over United States v. Donald J. Trump.

28 U.S. Code §455(a) provides that…

The criminal case against the former President is a 37-count indictment related to his alleged unlawful retention of national defense documents, conspiracy and obstruction of justice.

Tribe argued that Judge Cannon, in the earlier civil case filed by the former President last year, had not merely been overturned by the 11th Circuit Court of Appeal but also rebuked for what amounted to a lawless effort to interfere with an ongoing criminal investigation by the U.S. Department of Justice. Her unwarranted intervention was such that, in Tribe’s view, “no person could say” that the 455(a) standard mandating recusal “had not been met.”

The Harvard law professor is but one of many legal experts calling for Cannon’s recusal, as caselaw would appear to support their arguments…

In United States v. Kelley (1998), the U.S. 11th Circuit Court of Appeals observed:

The absence of a need to demonstrate actual bias was underscored in In re Boston’s Children’s First (1st Circuit 2001), a case where an appellate court granted a writ of mandamus compelling a judge’s recusal based upon remarks by a U.S. District Court Judge to a newspaper reporter. The court stressed that its ruling “in no way indicates a finding of actual bias or partiality” by the judge. Nevertheless, the court found she had abused her discretion in failing to recuse because her comments to the reporter gave rise to an “appearance of partiality.”

Recusal, or course, would not be mandated simply because, as two Trump-appointed judges and another arch conservative at the appeals level determined, Judge Cannon erred in earlier rulings both in respect to classified documents and her appointment of a special master. Her rulings, the three-judge appellate panel determined, amounted to an extraordinary effort to interfere with the same criminal investigation now before her, despite the absence of jurisdiction, let alone anything resembling a legal justification for her doing so.

The obligation to recuse is established by the appearance of Cannon’s previous effort to carve out special rules to protect the former President who appointed her. As the 11th Circuit Court of Appeal held in their unanimous decision late last year, those special rules “would defy our Nation’s founding principle that our law applies to all, without regard to numbers, wealth, or rank”…

Given the foregoing, Judge Cannon should promptly recuse on her own motion. Alternatively, in a letter [PDF], expressing concerns about bias, good government group Free Speech for People has asked the Chief Judge of the Southern District of Florida, where the case has been filed, to reassign the matter to another judge if Cannon fails to do so on her own accord.

If neither reassignment nor recusal are forthcoming, the government may choose to file a motion seeking a recusal — a motion that would have to be made and ruled upon by Cannon long before a trial date in order to avoid the issue of double jeopardy. If that motion is denied by Cannon, the government can then file a petition for issuance of a writ of mandamus with the 11th Circuit to compel her recusal.

The government has yet to offer any indication that it plans to do so.
