Washington DC - The Senate Judiciary Committee revealed at least three more undisclosed trips Supreme Court Justice Clarence Thomas took on GOP megadonor Harlan Crow's private jet.

The committee's chair, Senate Majority Whip Dick Durbin, announced the trips upon reviewing documents obtained from Crow's attorneys after receiving a subpoena authorization last year.

The undisclosed private jet travel included:

• a May 2017 flight from St. Louis, Missouri, to Kalispell, Montana, and onward to Dallas, Texas
  
• a March 2019 flight from Washington DC to Savannah, Georgia, and back
  
• a June 2021 flight from Washington DC to San Jose, California, and back

None of the three flights appeared on an amended 2019 financial disclosure report Thomas submitted just one week ago.

The news of the trips comes amid the conservative justice's ongoing scandal over reports of undisclosed luxury vacations and other favors financed by Crow, a Republican billionaire real-estate magnate from Texas.

"Nearly $4.2 million in gifts and even that wasn’t enough for Justice Thomas, with at least three additional trips the Committee found that he has failed to disclose to date," Durbin, a Democrat, said in a statement.

"The Senate Judiciary Committee’s ongoing investigation into the Supreme Court’s ethical crisis is producing new information – like what we’ve revealed today – and makes it crystal clear that the highest court needs an enforceable code of conduct, because its members continue to choose not to meet the moment."

Earlier this week, Republican Senator Lindsey Graham blocked legislation to create a Supreme Court ethics code.
