LA deployment tests limits of federal military authority

Three officials testified about the Los Angeles National Guard deployment, examining legal boundaries and the use of Title 10 in protests.

LA deployment tests limits of federal military authority

Three officials testified in the Los Angeles case over whether the deployment of roughly 4,000 California National Guard troops and some Marines violated the Posse Comitatus Act. The dispute centers on whether federal troops could assist local police during protests without crossing into domestic law enforcement. Governor Newsom has called the action an illegal power grab, while the Trump administration says Title 10 allows action when local forces cannot manage the situation.

Maj. Gen. Scott Sherman testified that he never heard the term rebellion used to describe the events in Los Angeles, a point that drew attention from the presiding judge. The case has been shaped by an appellate ruling that gave the president some deference to determine Title 10 applicability, while leaving open questions about the exact definition of rebellion. Separately, officials from DHS and Defense discussed the mission as protecting federal facilities and personnel, with limited police-like duties. The deployment has already been reduced, and Washington announced a separate, limited guard presence in the capital.

The case tests the boundary between state sovereignty and federal power when troops are asked to support law enforcement. It hinges on how the Posse Comitatus Act is interpreted and how flexible Title 10 can be in a fast-changing protest environment.

Second, the hearing exposes a broader tension in public life: can courts and lawmakers provide clear guardrails for executive action without magnifying political fallout? The outcome could reverberate in future crises, where the line between enforcement and protection is redrawn in real time.
