Republican donor Harlan Crow has refused to provide information to Senate Judiciary Democrats about his relationship with Supreme Court Justice Clarence Thomas, arguing that doing so would exceed Congress' authority and violate separation of powers principles. The request was made in response to questions about gifts Crow has given to Thomas that have not been disclosed, raising concerns about potential influence on Thomas' decisions. Crow's refusal is likely to fuel the controversy surrounding their relationship, with it yet to be seen if the committee will take any further action.
