A lawyer for Supreme Court Justice Clarence Thomas and his wife acknowledged that a Republican megadonor, Harlan Crow, paid for two years of private school tuition for Mark Martin, the great-nephew of Thomas, which was not disclosed.
Crow has made several financial contributions to Thomas and his family, including luxury vacations and property purchases, raising ethical questions.
Democrats are calling for stronger ethics rules for the Supreme Court, while Republicans have defended Thomas.
Crow's office issued a statement responding to questions but did not disclose the amount he paid for Martin's tuition.
