SAN FRANCISCO (AP) — The man accused of throwing a Molotov cocktail at the San Francisco home of OpenAI CEO Sam Altman pleaded not guilty Tuesday to charges of attempted murder and attempted arson.

Daniel Alejandro Moreno-Gama, wearing an orange jail uniform, did not speak as his attorney entered the pleas during his arraignment in state court. The 20-year-old also faces federal charges.
