The legal showdown between California Gov. Gavin Newsom and President Donald Trump takes center stage Thursday afternoon in a federal courtroom in San Francisco.

A protest against Immigrations and Customs Enforcement in Los Angeles has fueled similar demonstrations across the U.S. in recent days, with protesters arrested in New York, Philadelphia and other cities as Texas Gov. Greg Abbott said he would deploy the National Guard to several locations in the state.

It's been five days since anti-ICE demonstrations erupted in Los Angeles, some turning violent between protesters and law enforcement officers, prompting President Trump to deploy National Guard troops and hundreds of Marines.

The National Guard was deployed to Los Angeles County as anti-ICE protests continued to escalate Saturday afternoon and into the evening. The unrest is centered in the city of Paramount, California, where protesters clashed with federal authorities,

President Trump’s assertions that federal troops have saved the city from destruction did not appear to reflect reality.

The conflict between California Governor Gavin Newsom and Donald Trump over ICE raids in Los Angeles and the federalization of the National Guard has escalated today as the LAPD put the City of Angels on tactical alert over anti-deportation protests and resistance.
