Troops in LA: Trump Testing the Limits of Federal Authority By Send National Guard and Marines into City of Angels

On Tuesday, California Governor Gavin Newsom made an emergency plea to a federal court: block President Trump from using the National Guard and U.S. Marines to support immigration enforcement in the city. The request, filed as military vehicles rolled into LA, was as much about state sovereignty as it was about the optics of soldiers on American streets.

I remember walking through downtown LA during the 2020 protests—helicopters overhead, the National Guard stationed at City Hall, the city’s nerves exposed. This week, the mood is even more electric, with the added weight of a legal battle that could redefine the boundaries between state and federal authority.

What’s at Stake: State Rights vs. Federal Muscle

At the heart of California’s lawsuit is the Tenth Amendment, that perennial shield of state power. Newsom and Attorney General Rob Bonta argue that Trump’s order to deploy roughly 4,000 National Guard members and 700 Marines—ostensibly to secure perimeters during immigration raids—amounts to an “imminent harm to State Sovereignty.” The state’s legal team claims the move not only deprives California of vital resources but also risks escalating tensions and promoting unrest, rather than quelling it.

The Trump administration, for its part, insists the deployment is necessary to restore order after protests against immigration raids turned violent. In a speech at Fort Bragg, Trump described the protesters as “a foreign enemy,” vowing to “liberate Los Angeles and make it free, clean, and safe again.” The rhetoric is as charged as the legal arguments, and both sides seem to be digging in for a protracted fight.

The Legal Chessboard: Judge Breyer’s Calculated Move

U.S. District Judge Charles Breyer, presiding over the case in San Francisco, declined to grant California’s request for an immediate restraining order. Instead, he gave the Trump administration 24 hours to respond and scheduled a hearing for Thursday, June 12. The judge’s decision means the military presence in LA will continue—at least for now—while both sides prepare their legal salvos.

The Justice Department called California’s request “highly unusual and indeed non-justiciable under constitutional principles,” arguing that the president’s authority to deploy troops in such circumstances is well established. But Newsom’s team counters that there is “no invasion or rebellion” in Los Angeles, and that the federal government is overstepping its bounds by using the military for domestic law enforcement.

On the Ground: Tension, Uncertainty, and Political Theater

For Angelenos, the legal wrangling is more than an abstract debate. The city is bracing for more protests, and local officials worry that the presence of federal troops could make things worse. LAPD Chief Jim McDonnell warned that the arrival of Marines and National Guard units—without clear coordination—poses “a significant logistical and operational challenge.”

Meanwhile, the cost of the deployment is already making headlines:$134 million, according to a Defense Department official, mostly for travel, housing, and food. That’s a staggering sum for a mission whose legal footing is still being contested.

The Broader Implications: A Test for American Federalism

This isn’t just about Los Angeles, or even California. The outcome of this case could set a precedent for how—and when—the federal government can use military force within U.S. borders, especially over the objections of state leaders. It’s a test of American federalism, played out in real time, with real consequences for the people on the ground.

As I watch this unfold, I can’t help but think of past moments when the balance of power between Washington and the states was up for grabs. The echoes of history are unmistakable, but the stakes feel uniquely urgent in this moment of national polarization.

What Comes Next

Thursday’s hearing will be closely watched—not just by legal scholars and politicians, but by every Angeleno wondering what tomorrow will bring. Will Judge Breyer side with California’s plea for autonomy, or uphold the president’s sweeping authority? Either way, the decision will reverberate far beyond the courtroom, shaping the contours of American democracy for years to come.
