“While some of the hospitality, such as stays in personal homes, may not have required disclosure, Thomas appears to have violated the law by failing to disclose flights, yacht cruises and expensive sports tickets, according to ethics experts,” the report says.

At least four other House Democrats also called for Thomas’ resignation, including Reps. Pramila Jayapal (D-Wash.), Bill Pascrell (D-N.J), Gerry Connolly (D-Va.) and Hank Johnson (D-Ga.).

“Unprecedented. Stunning. Disgusting. The height of hypocrisy to wear the robes of a #SCOTUS and take undisclosed gifts from billionaires who benefit from your decisions,” Jayapal posted on X. “Resign.”

The Supreme Court’s Public Information Office did not immediately respond to POLITICO’s request for comment.

Democrats in the Senate have attempted to push legislation that would reform the Supreme Court’s ethical guidelines in an effort to increase transparency. That bill has passed committee but is unlikely to get through a full Senate.

“I said it would get worse; it will keep getting worse,” Sen. Sheldon Whitehouse (D-R.I.), who helped spearhead the bill, said on X in response to Thursday’s report.

“The latest ProPublica revelation of unreported lavish gifts to Justice Clarence Thomas makes it clear: these are not merely ethical lapses,” Senate Judiciary Chair Dick Durbin wrote on X. “This is a shameless lifestyle underwritten for years by a gaggle of fawning billionaires.”

The ProPublica report builds on the outlet’s work that has unveiled an array of unreported gifts Thomas has received from wealthy benefactors and generated questions around the court’s ethical guidelines. The publication has reported that Thomas accepted regular luxury vacations, trips on private jets and yachts, as well as thousands in tuition dollars for his relative from Texas billionaire Harlan Crow.

In response to reports about accepting luxury vacations in April, Thomas stated that he received guidance that personal hospitality from friends without business before the court did not need to be reported.
