Progressive lawmakers and organizers on Wednesday urged U.S. Supreme Court Justice Samuel Alito to recuse himself from cases related to the Jan. 6 attack on the U.S. Capitol, and to testify before Congress about two flags sympathetic to insurrectionists that were displayed outside his two homes.

U.S. Supreme Court Chief Justice John G. Roberts Jr. told leading Democrats on the U.S. Senate Judiciary Committee last week he will not meet with them to discuss the court’s code of ethics, following revelations of displays of politically oriented flags at the homes of Justice Samuel Alito.
