Tensions in Los Angeles escalated Sunday as thousands of protesters took to the streets in response to President Donald Trump’s extraordinary deployment of the National Guard, blocking off a major freeway and setting self-driving cars on fire as law enforcement used tear gas,

Newsom said Trump's presidential memorandum from Saturday night was not issued through the "governor of the State," arguing that is unlawful under federal law.

National Guard troops were stationed around federal government buildings, as police and protesters clashed in separate demonstrations over federal immigration raids in Los Angeles.
