ProPublica released a report Thursday revealing new details about Clarence Thomas’ history of accepting lavish gifts while serving as a US Supreme Court Justice. According to the report, Thomas failed to disclose millions of dollars worth of gifts from several multi-millionaires who shared his conservative views. The report specifically names H. Wayne Huzienga, David Sokol, Paul Novelly and Harlan Crow, all finance and oil tycoons.

The newly uncovered gifts included skybox tickets to University of Nebraska football games, private flights to resorts owned by his benefactors and golf club initiations valued at $150,000. Thomas also used the Supreme Court building to host galas for the Horatio Alger Association, a college scholarship nonprofit. Huzienga, Sokol, Novelly, and Crow were all members of the Horatio Alger Association as well. The judiciary code of conduct explicitly advises federal judges not to use their positions to fundraise for outside organizations. The code is not mandatory for Supreme Court Justices, but it is customary for them to adhere to it in practice.

While Thomas is not the only Supreme Court Justice to receive gifts, experts say the quantity of gifts and lack of disclosure is unprecedented. Because the gifts were kept secret by Thomas, ProPublica investigated emails, flight records, security details and other information to uncover Thomas’ activities. They also interviewed over 100 witnesses. In the course of their greater investigation of Justice Thomas, ProPublica has shed light on other inappropriate gifts from conservative donors.

Thomas and his representatives insist that these gifts were exchanged for friendship, not political, reasons. Mark Paoletta, Thomas’s friend and lawyer to Thomas’s wife Ginni, accused ProPublica of launching a partisan attack on Thomas and said the report “does not mention Judicial Conference’s previous guidance that Justice Thomas didn’t have to disclose trips w/ friends.” 

In their report, ProPublica acknowledged that there was little evidence so far that the gifts directly impacted any Supreme Court decisions by Thomas, yet critics like Representative Ted Lieu (D-CA) say that the broader context of behavior around the gifts signals corruption. “Would billionaires have given Justice Clarence Thomas massive gifts if he was just a law clerk?” Lieu posted on his Twitter account, “NO. That’s what makes this corrupt.”
