National Guard troops already have temporarily detained civilians in the Los Angeles protests over immigration raids.

The National Guard in Los Angeles has detained anti-ICE protesters while providing security for immigration operations, with officials expecting protests to escalate.

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.

Large crowds gathered near a federal detention center in downtown Los Angeles Friday protesting immigration raids that had taken place throughout the city.

The Guard’s arrival marks a potentially volatile phase in Trump’s push to ramp up deportations and in his contentious relationship with state and local authorities.
