Dick Durbin, Chairman of the Senate Judiciary Committee, has invited Chief Justice John Roberts to testify on Supreme Court ethics rules in light of reports of Justice Clarence Thomas' undisclosed acceptance of luxury gifts and real estate transactions. Durbin believes Roberts is an articulate and well-schooled man who would do well in responding to senators' questions, and that Thomas' reported conduct would amount to a violation of law if he were a circuit court judge. The hearing is expected to take place in early October.
