Ruling on military involvement in immigration enforcement

A federal judge in San Francisco weighs whether the Trump administration violated federal law by sending National Guard troops to accompany immigration agents in Southern California.

Judge to decide if Trump broke law with National Guard deployment to LA

SAN FRANCISCO AP — A federal judge in San Francisco heard three days of testimony on whether the Trump administration violated the Posse Comitatus Act by using National Guard troops to support immigration raids in Southern California. California argues the act bars military involvement in civilian law enforcement, while the defense says the Guard was called into federal service under a presidential authority that allows action when regular forces cannot execute the laws. Testimony from federal and military officials focused on how the troops were used and whether they performed law enforcement tasks beyond protection.

The proceedings described deployments where Guard members guarded federal property, helped guard detention centers, and, in some cases, detained people or blocked streets. The government contends troops were not acting as police, while California says there was an active role in enforcing civilian law. The judge’s decision could determine whether remaining troops stay under federal direction or return to state control, and it may shape how similar actions are handled in California and elsewhere.

This case tests a core question of governance: where does military power end and civilian policing begin? The government argues a president can call the guard into federal service when state capacity is overwhelmed, while California contends that any direct enforcement by troops crosses a constitutional line. The outcome will send a signal about how the United States balances security needs with constitutional limits in a politically charged moment.

Beyond the facts of the trial, the case highlights ongoing tensions over immigration policy and how courts check executive power. A ruling that tightens the line could curb future deployments, while a ruling that broadens authority could embolden federal actions in other states and undercut state sovereignty.
