Twitter community adds a context note to popular account's tweet:  A popular Twitter account for Harry Sisson, whose bio indicates that he is a 20-year-old Democrat, tweeted, “Holy shit. Justice Alito just said that Congress has NO authority to regulate the Supreme Court. WTF? This guy thinks he has unlimited authority. And Republicans allow him: 'No provision in the Constitution gives them the authority to regulate the Supreme Court. Period.'" Twitter added a label to the post that read "Readers added context they thought people might want to know.” The added context read "Congress has no per se authority to regulate SCOTUS. Checks on the Judicial Branch by the Legislative Branch are limited to 'Advice and Consent' for appointment of judges and removal from office via Impeachment by the House of Representatives and Conviction by the Senate." The note included two links to the constitution to support the assertion. The label is part of Twitter’s Community Notes system.
