A Senate investigation revealed systemic ethics violations among Supreme Court justices, particularly Clarence Thomas, who failed to disclose luxury trips valued at over $4.75 million since 1991. The report, part of a two-year inquiry by the Senate Judiciary Committee, emphasizes the need for Congress to create enforceable ethical standards, amid Republican resistance as they prepare to control the Senate in January. The investigation highlights conflicts of interest and failures to recuse from cases related to political interests. Democrats call for reform, but a GOP majority may hinder progress on ethical oversight.
