Protests have continued in the Los Angeles area since Immigration and Customs Enforcement conducted mass arrests in the area Friday.

President Donald Trump on Tuesday did not rule out invoking the Insurrection Act if necessary to squash violence at the Los Angeles protests. “If there’s an insurrection, I would certainly invoke it,” Trump said.

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.
