The Supreme Court on April 29 turned away billionaire entrepreneur Elon Musk’s attempt to contest a deal he reached with the U.S. Securities and Exchange Commission (SEC) that required a legal monitor to review his social media posts.

Mr. Musk claimed in court papers that the SEC has been engaged in an “ongoing campaign” against him.
