This appears to be the first time in decades that a state's National Guard was activated without a request from its governor.

The protests began Friday after Immigration and Customs Enforcement agents carried out coordinated raids across Los Angeles, detaining dozens of workers at warehouses and other worksites. The arrests sparked immediate backlash, with demonstrators converging outside federal buildings, blocking freeways, and in some cases clashing with police.

Demonstrators hit the streets again in L.A. after President Trump deployed the National Guard due to protests against ICE raids.

LOS ANGELES (AP) — The Marines that deployed to Los Angeles on orders from President Donald Trump have not yet been called to respond to the city’s immigration protests and are there only to protect federal property, the Marine Corps commandant said Tuesday.

The last time a president sent the National Guard to respond to violence on Los Angeles streets followed a backlash against police brutality in 1992.

Trump has deployed 4,000 National Guardsmen and 700 Marines to LA. Tensions are escalating for a third day in Los Angeles after protests against Immigration and Customs Enforcement gripped the city, with demonstrators clashing with law enforcement and setting vehicles on fire downtown.

The Pentagon's deployment of about 700 Marines to Los Angeles to join the National Guard's response to immigration protests follows weeks of rapid-fire developments as President Donald Trump pursues his top domestic priority for mass deportations.
