Senators Angus King and Lisa Murkowski have introduced the Supreme Court Code of Conduct Act, which would require the Supreme Court to implement a code of conduct and designate an official to review potential conflicts of interest. Chief Justice John Roberts has declined an invitation to testify at a committee hearing on the Supreme Court's ethics rules, but the justices have released a statement stressing their commitment to ethics principles. The bill is an important step in ensuring that the Supreme Court is held to the highest ethical standards.
