A conservative think tank has filed an ethics complaint against Supreme Court Justice Ketanji Brown Jackson.

The Center for Renewing America’s complaint, filed Monday and addressed to the Judicial Conference Secretary, accuses the justice of appearing to “have willfully failed to disclose required information regarding her husband’s medical malpractice consulting income for over a decade.”

It also states, “There is reason to believe that Justice Jackson may have failed to report the private funding sources of her massive investiture celebration at the Library of Congress in her most recent financial disclosure.” 

“Given the need to ensure the equal application of the law and the tendency of these violations to create serious recusal issues and conflicts of interest, the Conference’s prompt attention is of paramount public importance,” the complaint reads.

The Center for Renewing America said Brown should be referred to Attorney General Merrick Garland regarding its complaint on disclosure of her husband’s income.

The Hill has reached out to the Supreme Court for comment on the matter.

The center was founded in 2021 by Russ Vought, former director of the Office of Management and Budget under former President Trump.

The complaint comes shortly after a letter by some House Democrats in which they asked Supreme Court Justice Clarence Thomas to recuse himself from a case about whether former President Trump is immune from prosecution over charges of attempting to overturn the 2020 election.

“[W]e strongly implore you to exercise your discretion and recuse yourself from this and any other decisions in the case of United States v. Trump,” the group of Democrats, which included Reps. Hank Johnson (Ga.), Jamie Raskin (Md.), Sheila Jackson Lee (Texas) and Alexandria Ocasio-Cortez (N.Y.), wrote in the letter.

In the letter, the House Democrats highlighted the fact that Ginni Thomas, Thomas’s wife, was a backer of incorrect claims by former President Trump about the 2020 election. Thomas was interviewed by the House select committee on the Jan. 6 attack. The panel said she repeated the aforementioned claims.
