Tensions escalated after President Donald Trump called up the National Guard over the objections of state and city leaders.

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.
