Anthony Brown’s Latest Anti-Trump Lawsuit: Maryland Taxpayers Foot the Bill for Another Political Stunt

Maryland’s attorney general is asking a federal court to halt an ICE detention facility in Washington County

By Michael Phillips | MDBayNews

Maryland Attorney General Anthony Brown announced Tuesday that his office has filed an emergency motion in federal court seeking to halt construction of a proposed ICE detention facility in Washington County. The move, framed by Brown as a defense of Maryland’s environment and communities, is already drawing criticism as yet another taxpayer-funded legal stunt aimed at scoring political points against the Trump administration.

A closer look at the lawsuit—and the legal arguments underlying it—suggests Brown’s latest effort is unlikely to succeed in court. Instead, it appears to be part of a broader pattern: aggressive political litigation designed more for headlines than for legal durability.

The Lawsuit at the Center of the Fight

The state’s filing seeks a temporary restraining order (TRO) to stop federal authorities from converting a large warehouse near Williamsport, Maryland, into an immigration detention facility capable of housing up to 1,500 detainees. The lawsuit argues that federal agencies violated the National Environmental Policy Act (NEPA) by moving forward with the project without conducting environmental reviews or allowing public input.

Brown’s office claims construction could harm nearby waterways, ecosystems, and local infrastructure, including sewage systems and streams feeding into the Potomac River watershed.

But the legal argument rests on a thin premise: that the purchase and conversion of an existing warehouse into a detention facility automatically requires a full environmental review before any renovation begins.

That claim is far from settled law—and courts have repeatedly rejected similar attempts by states to weaponize environmental statutes to block federal policy.

Why the Emergency Motion Is Likely to Fail

To obtain a temporary restraining order, Maryland must prove four elements:

1. Likelihood of success on the merits
2. Irreparable harm without the injunction
3. Balance of equities in its favor
4. Public interest supporting the injunction

Each of these elements presents serious problems for Brown’s case.

1. Weak Claim of Irreparable Environmental Harm

The state argues that construction could harm streams, endangered species, and wastewater systems near the site.

But courts typically require specific, imminent environmental damage, not speculative projections.

In this case, the property is already:

• A fully constructed industrial warehouse
• Located in a commercial logistics zone
• Previously approved by local permitting authorities

The federal government is not building a new facility from scratch—it is retrofitting an existing structure.

That distinction matters. Courts routinely rule that renovation of existing facilities does not automatically trigger NEPA environmental impact reviews unless major new environmental disruption is shown.

Brown’s filing largely relies on hypothetical scenarios: sediment runoff, sewer upgrades, or possible infrastructure stress. Those types of arguments rarely meet the “imminent harm” standard required for emergency injunctions.

2. NEPA Does Not Automatically Apply the Way Maryland Claims

The state’s entire lawsuit hinges on the claim that DHS and ICE violated NEPA by failing to prepare an environmental impact statement or environmental assessment before moving forward.

But NEPA contains numerous exceptions and discretionary standards.

Federal agencies may bypass full environmental reviews if:

• The action falls within a categorical exclusion
• The environmental effects are minimal
• The action involves existing facilities or infrastructure

In many cases involving detention facilities or law enforcement buildings, courts have ruled that facility conversions fall within categorical exclusions.

If DHS asserts such an exclusion—as it often does in similar cases—the court may defer to the agency’s judgment.

Maryland’s lawsuit appears to assume that NEPA applies without first proving that threshold issue.

That is a major legal hurdle.

3. The Federal Government Controls Immigration Facilities

Even if Maryland could raise environmental concerns, federal courts traditionally give wide deference to the federal government on immigration enforcement and detention infrastructure.

The Constitution places immigration authority squarely with the federal government.

Courts have repeatedly rejected state attempts to interfere with federal immigration operations using indirect legal arguments such as environmental regulations.

If the judge views the lawsuit as an attempt to obstruct immigration policy rather than protect environmental resources, Maryland’s chances of obtaining an injunction drop dramatically.

4. Timing Undermines the “Emergency”

Perhaps the most damaging weakness in Brown’s filing is timing.

The federal government reportedly purchased the property in January 2026 for more than $100 million and publicly acknowledged its intended use weeks later.

Yet Maryland waited until late February to file suit and only now seeks an “emergency” restraining order.

Courts often reject emergency motions when the plaintiff delayed filing, reasoning that a true emergency would have prompted immediate legal action.

In other words: if this was truly an urgent environmental crisis, why did the state wait?

Another Lawsuit in a Growing Pattern

Brown’s legal challenge is part of a broader strategy that has become increasingly common among Democratic attorneys general: filing high-profile lawsuits against federal policies to generate political attention.

Maryland has joined or filed numerous lawsuits targeting federal immigration policy, border enforcement initiatives, and other Trump administration priorities.

These cases often follow the same formula:

1. File a lawsuit immediately after a federal policy announcement
2. Seek an emergency injunction
3. Generate national media coverage
4. Lose or settle quietly months later

For politicians with higher ambitions, these lawsuits function as a form of political theater—signaling ideological opposition while shifting the financial burden of litigation onto taxpayers.

The Politics Behind the Case

Anthony Brown is no stranger to national political aspirations.

A former lieutenant governor and congressional candidate, Brown has increasingly positioned himself as a national Democratic voice on issues such as immigration and civil rights.

Filing lawsuits against a Republican administration helps elevate that profile.

But critics argue the strategy comes at a cost.

Each major lawsuit requires:

• State attorneys
• court filings
• federal litigation
• potential appeals

All funded by Maryland taxpayers.

And if the court ultimately dismisses the case—as many legal observers expect—the practical result will be little more than a temporary delay and a stack of legal bills.

The Reality: Federal Immigration Policy Will Continue

Even if Maryland temporarily slows the project, the federal government retains the authority to build and operate immigration detention facilities wherever it chooses, subject only to federal law.

If this site is blocked, ICE can simply move operations elsewhere.

That raises the question: what exactly is Maryland trying to accomplish?

Stopping federal immigration enforcement is beyond the power of the state. At most, Brown’s lawsuit can delay a single facility while the broader federal system continues operating.

In that sense, the case appears less like a serious legal challenge and more like a political statement.

The Bottom Line

Attorney General Anthony Brown is asking a federal court to halt a federal immigration facility based on speculative environmental claims tied to the renovation of an existing warehouse.

Courts have historically been skeptical of such arguments—especially when they interfere with federal immigration authority.

Which means Maryland taxpayers may once again be funding a lawsuit that generates headlines today but collapses in court tomorrow.

For Brown, that may be enough.

For the rule of law—and for taxpayers—it raises a far more uncomfortable question:

Is Maryland’s attorney general acting as the state’s top lawyer, or as a partisan political activist using the courts as a campaign platform?
