The Supreme Court is returning to a new term with familiar topics such as guns and abortion, as well as concerns about ethics swirling around the justices. The year also will have a heavy focus on social media and how free speech protections apply online. The new term begins on Monday. A big unknown is whether the court will be asked to weigh in on any aspect of the criminal cases against former President Donald Trump or on efforts in some states to keep Trump off the 2024 presidential ballot because of his role in trying to overturn the results of the last presidential contest.
