 A Cleveland police officer is shot and killed while trying to serve an assault warrant early today. Police say the 27-year-old officer was one of multiple officers on the scene as the suspect reportedly opened fire during an attempted getaway on a bicycle. About 150 million Americans are under heat alerts in 21 states with triple-digit heat expected in parts of California this week. That can also elevate the wildfire risk with some communities canceling fireworks as a result.
