Marcellus Williams, a Missouri man facing execution for the 1998 murder of social worker Lisha Gayle, has appealed to the U.S. Supreme Court after both the Missouri governor and state supreme court rejected his requests for clemency. Williams, who maintains his innocence, argues that similar issues in his case parallel those in the Richard Glossip case, which the Supreme Court is set to review in October. Meanwhile, Justice Samuel Alito temporarily stayed a Fifth Circuit ruling declaring parts of the Horseracing Integrity and Safety Act unconstitutional, preserving the law aimed at preventing doping in horse racing. The Horseracing Integrity and Safety Authority warned that allowing the ruling to take effect could lead to increased horse deaths and corruption in the industry. The law, enacted following several high-profile scandals, had previously been amended to address constitutional concerns but faces ongoing legal challenges. Alito has asked opponents of the law to respond to the stay request by September 30.
