The Supreme Court did not disclose its longstanding financial ties with former Homeland Security Secretary Michael Chertoff even as it touted him as an expert who independently validated its investigation into who leaked the draft opinion overturning Roe v. Wade.

The court’s inquiry, released last week with Chertoff’s endorsement, failed to identify who was responsible for the unprecedented leak. The decision to keep the relationship with Chertoff quiet is a reflection of a pattern of opacity at the nation’s highest court, whose rulings affect every American. the court in recent years has privately contracted with The Chertoff Group for security assessments, some broadly covering justices’ safety and some specifically related to Covid-19 protocols at the court itself.

The estimated payments to Chertoff’s risk assessment firm, for consultations that extended over several months and involved a review of the justices’ homes, reached at least $1 million. The exact amount of money paid could not be determined. Supreme Court contracts are not covered by federal public disclosure rules and elude tracking on public databases.
