Supreme Court ethics breach? New gift to Justice Thomas surfaces.

A Republican megadonor paid two years of private school tuition for a child raised by Supreme Court Justice Clarence Thomas, who did not disclose the payments, a lawyer who has represented Mr. Thomas and his wife acknowledged Thursday.

The revelation of tuition payments made by Dallas billionaire Harlan Crow is the latest example of Mr. Crow’s generosity to Mr. Thomas and his family that has raised questions about Mr. Thomas’ ethics and disclosure requirements more generally. The payments, along with the earlier examples of Mr. Crow’s financial ties to Mr. Thomas, were first reported by the nonprofit investigative journalism site ProPublica.

ProPublica reported Thursday that Mr. Crow paid tuition for Mr. Thomas’ great-nephew Mark Martin. Mr. Thomas and his wife, Virginia, raised Mr. Martin from the age of 6.
