The chair of the Senate Finance Committee has asked Texas billionaire and conservative activist Harlan Crow to provide Congress with a detailed list of undisclosed gifts and payments benefiting Supreme Court Justice Clarence Thomas, including private real estate transactions and the use of Crow’s private jet and superyacht. In a letter sent to Crow Monday, Democratic Senator Ron Wyden wrote, “The secrecy surrounding your dealings with Justice Thomas is simply unacceptable. The American public deserves a full accounting of the full extent of your largesse towards Justice Thomas, including whether these gifts complied with all relevant federal tax and ethics laws.” Meanwhile, Bloomberg News is reporting Justice Thomas failed to recuse himself from a 2005 Supreme Court decision to reject a case which benefited the Trammell Crow Residential Company, a real estate firm named after Harlan Crow’s father that was partly owned by the Crow family. Harlan Crow was CEO and chair of the board at the time.
