Billionaire GOP donor paid for Justice Clarence Thomas' relative's private school tuition.

A new report by ProPublica reveals that a GOP megadonor, Harlan Crow, paid for the boarding school tuition of Supreme Court Justice Clarence Thomas' grandnephew, Mark Martin, and the justice did not report the financial assistance for the child he helped raise on his annual disclosures. This is the latest revelation raising ethical questions around the high court. Thomas has previously accepted lavish trips and gifts from Crow, which have gone mostly unreported on the justice's financial disclosures. The current ethics rules for the justices are being criticized as too lax.
