Supreme Court Justice Clarence Thomas is acknowledging that he took three trips last year aboard a private plane owned by Republican megadonor Harlan Crow.

It’s the first time in years that Thomas has reported receiving hospitality from Crow. In a report made public Thursday, the 75-year-old justice said he was complying with new guidelines from the federal judiciary for reporting travel.

The filing comes amid a heightened focus on ethics at the high court that stems from a series of reports revealing that Thomas has for years received undisclosed expensive gifts, including international travel, from Crow, a wealthy businessman and benefactor of conservative causes. Crow also purchased the house in Georgia where Thomas’s mother continues to live and paid for two years of private school tuition for a child raised by Thomas and his wife, Ginni.
