The Supreme Court on Thursday indicated it has not yet identified the source of the leak of a draft opinion that showed the court voting in favor of overturning Roe v. Wade’s abortion protections.

In a public report detailing the investigation into the May leak of the draft Dobbs v. Jackson Women’s Health Organization opinion, the court said it has conducted interviews with almost 100 employees and forensic analysis.

“The team has to date been unable to identify a person responsible by a preponderance of the evidence,” the report states.

Chief Justice John Roberts assigned the court’s marshal to investigate the leak immediately after it was published by Politico last year.
