Justice Amy Coney Barrett has expressed her support for the Supreme Court to adopt a code of conduct, joining several of her colleagues who have already publicly backed the idea. Congress has been pushing for the Supreme Court to lay out a binding set of policies, and Barrett's support is a significant step forward in the process. It is unclear when the code of conduct may be adopted, but it is likely to be welcomed by those who have been pushing for greater transparency and accountability from the nation's highest court.
