TOM HOMAN SHOULD BE ALLOWED TO ARREST EVERY SINGLE SANCTUARY CITY MAYOR!
THEY WANT TOM HOMAN TO ARREST SANCTUARY MAYORS — BUT ONE LINE IN THE CONSTITUTION STANDS IN THE WAY
The demand sounds simple.
If a mayor orders city employees not to help federal immigration agents, arrest the mayor.
If a sanctuary city releases an immigrant after ICE asks for more time, prosecute the official who allowed it.
If local leaders tell residents how to respond to federal raids, charge them with obstruction.
Supporters of President Donald Trump’s immigration crackdown increasingly describe those actions as open defiance of federal law. They argue that mayors in New York, Chicago, Boston, Denver, Minneapolis and other Democratic-led cities are shielding people who entered or remained in the country illegally.
Tom Homan has repeatedly encouraged that view.
Before returning to government, he said he was willing to put Denver Mayor Mike Johnston in jail if Johnston crossed the line from political opposition into active interference. In a later interview, Homan asked why a mayor or governor should be immune if an ordinary citizen could be arrested for knowingly hiding someone from immigration authorities.
The rhetoric has now become a national call for handcuffs.
But there is one legal question capable of collapsing the entire argument:
Did the mayor actually obstruct a federal officer—or did the city merely refuse to provide its own officers, jails and money to help?
Those actions may look identical to angry voters.
Under the Constitution, they are not.
The federal government controls immigration law. ICE can enter sanctuary cities, investigate cases and arrest people subject to removal. Local officials cannot lawfully block agents, destroy evidence, hide a named fugitive or tip off a target during a specific operation.
But Washington generally cannot force a state or city to administer a federal program.
That principle is called the anti-commandeering doctrine.
It means a city may often decline to turn its police department into an extension of ICE without committing a federal crime.
That is the hidden legal line behind the arrest demands.
Cross it one way, and a mayor may be exercising constitutional authority.
Cross it the other, and the same mayor could face subpoenas, prosecution and prison.
HOMAN CANNOT PERSONALLY ARREST A MAYOR
The first misconception concerns Homan himself.
The title “border czar” sounds like command authority over every part of immigration enforcement. Homan is a White House official who coordinates and publicly represents the administration’s deportation strategy. He previously served as acting director of ICE and possesses decades of law-enforcement experience.
He is not a prosecutor.
He does not personally issue criminal indictments.
He cannot order a mayor jailed because the mayor criticized ICE or adopted a policy Homan dislikes.
A lawful arrest would normally require federal investigators to develop probable cause that a specific crime occurred. The Justice Department would decide whether to seek charges. A judge or grand jury would become involved, depending on the case.
Homan can refer conduct for investigation.
He can coordinate operations.
He can increase the number of ICE agents sent into a city.
He can publicly pressure local officials.
The decision to arrest an elected official still must travel through the criminal-justice system.
That distinction matters because the current debate often treats arrest as a political option available whenever a mayor refuses cooperation.
It is not.
A prosecutor must identify a statute and evidence satisfying every element of that statute.
THE CRIME HOMAN HAS CITED
Homan has pointed to 8 U.S.C. §1324, the federal law that makes it a crime in certain circumstances to knowingly conceal, harbor or shield an undocumented immigrant from detection.
The law is real.
It has been used against people who hid individuals in homes, transported them to avoid authorities or participated in organized schemes designed to defeat immigration enforcement.
It does not automatically turn every sanctuary policy into criminal harboring.
Prosecutors would need evidence that an official knew a particular person was unlawfully present and took action that amounted to concealing, harboring or shielding that person from detection.
A general city rule stating that local police will not ask crime victims about immigration status is not the same as hiding a named fugitive in City Hall.
A policy declining to hold people beyond their scheduled release dates is not automatically the same as helping someone escape through a back door while ICE waits outside.
The facts matter.
So does intent.
A mayor can strongly oppose federal enforcement without possessing the criminal purpose required by a harboring or obstruction statute.
The government may believe the local policy makes its work harder.
Making federal work harder is not always a federal crime.
THE DETAINER THAT CHANGES THE ANALYSIS
Much of the conflict involves ICE detainers.
When a person is already held in a local jail, ICE may send a request asking the jail to provide advance notice of release or keep the person for additional time so federal agents can assume custody.
Supporters of the administration describe refusal as releasing a dangerous immigrant onto the street instead of handing that person safely to ICE.
That public-safety argument can be powerful.
The legal document is still generally a request, not a judicial command.
Federal appellate courts have held that ICE detainers do not compel local agencies to continue holding someone. In Galarza v. Szalczyk, the Third Circuit concluded that immigration detainers could not force state or local police to perform federal detention work.
The case involved a United States citizen mistakenly held for several days because of an ICE detainer.
That mistake explains why many cities require a judicial warrant before extending custody.
Keeping someone after the state-law basis for detention has ended can create Fourth Amendment liability if there is no adequate legal authority.
A mayor who orders jails not to honor warrantless detainers may say the city is protecting taxpayers from unlawful-detention lawsuits.
Homan may say the mayor is forcing agents to make riskier arrests in homes, streets and workplaces.
Both can be true.
The argument does not automatically create a crime.
THE CONSTITUTIONAL WALL
The Supreme Court has repeatedly said the federal government cannot simply command state officials to run a federal regulatory program.
In Printz v. United States, the Court rejected a federal requirement forcing local law-enforcement officers to perform background-check duties for a federal gun program.
In Murphy v. NCAA, the Court reaffirmed that Congress generally lacks power to issue direct orders to state governments.
Immigration is a federal responsibility.
That gives Washington authority to enforce federal immigration law throughout the country.
It does not give Washington unlimited power to conscript city employees.
This creates the legal foundation for many sanctuary policies.
A city may decide that its police officers will focus on local crime rather than civil immigration enforcement.
It may restrict the use of city funds, buildings or databases.
It may decline voluntary agreements with ICE.
It may require federal agents to obtain judicial warrants before entering nonpublic city facilities.
The federal government remains free to enforce its laws using federal personnel.
The city generally cannot physically interfere with those agents.
That last sentence is where the criminal danger begins.
REFUSAL IS NOT OBSTRUCTION
Imagine two mayors.
The first mayor says:
“Our police will not ask witnesses about immigration status. Our jail will release people when state law requires release. ICE may perform its own operations, but city employees will not participate without a judicial warrant.”
The second mayor receives confidential information that ICE will arrest a named individual at a specific address. The mayor orders an employee to warn the target, moves the target into a hidden government building and directs city vehicles to block federal agents.
The first scenario is noncooperation.
The second may contain evidence of active obstruction, concealment or conspiracy.
Political arguments often collapse the two.
Criminal law cannot.
The government must prove what the official actually did.
Publicly criticizing ICE is protected speech.
Teaching residents that they may request a warrant before allowing agents into a home is generally not obstruction; it communicates existing constitutional rights.
Refusing to volunteer city resources may be protected by federalism.
Lying to investigators, destroying records, physically blocking officers or deliberately hiding a person can produce a very different case.
A mayor is not immune because of elected office.
A mayor is also not guilty merely because federal officials call the city a sanctuary.
THE GOVERNMENT IS ALREADY TESTING THE LINE
The Trump Justice Department has moved aggressively against sanctuary jurisdictions.
It published a list of states and cities accused of obstructing immigration enforcement.
It filed civil lawsuits against New York City, Los Angeles, Maryland, Connecticut, New Mexico, Minnesota and other jurisdictions.
Those suits argue that particular state or local laws conflict with federal immigration statutes, discriminate against federal operations or violate the Constitution’s Supremacy Clause.
Civil litigation is significant.
It asks courts to invalidate policies and order governments to stop enforcing them.
It is not the same as arresting the mayor.
The Justice Department has also used grand-jury subpoenas.
Federal prosecutors subpoenaed Minnesota Gov. Tim Walz, Attorney General Keith Ellison and the mayors of Minneapolis and St. Paul during an investigation into alleged obstruction of immigration operations.
A subpoena does not prove a crime.
It compels testimony or records so a grand jury can determine whether evidence supports charges.
The investigation reflects the administration’s theory that public statements, coordination and local policies may have moved beyond lawful refusal.
The officials call it political intimidation.
No final court judgment has established that the mayors committed a federal offense.
That unresolved status is exactly why arrest demands are premature.
THE EXAMPLE THAT SUPPORTS HOMAN’S WARNING
Federal officials can point to cases where obstruction charges were based on concrete acts rather than sanctuary policies.
In 2025, the Justice Department charged a Wisconsin judge after alleging that she helped an immigrant avoid federal agents waiting to arrest him at a courthouse.
The government said the judge directed agents away from the courtroom and allowed the man to leave through another door.
The defense disputed the government’s account and legal theory.
The case illustrates the kind of evidence prosecutors seek.
A specific target.
Federal agents present for a specific arrest.
An alleged action designed to help the target evade them.
That is different from a mayor signing an ordinance that applies generally to city employees.
The example strengthens Homan’s claim that officials can be prosecuted when they actively interfere.
It weakens the idea that every sanctuary mayor can be arrested simply for refusing cooperation.
THE SUPREMACY CLAUSE DOES NOT ANSWER EVERYTHING
Administration lawyers emphasize the Supremacy Clause.
Federal law is the supreme law of the land. States cannot nullify immigration statutes or make federal enforcement illegal.
That principle is fundamental.
It does not erase the Tenth Amendment.
The two doctrines operate together.
A state may not directly regulate federal agents or prohibit them from carrying out lawful duties.
The federal government may not automatically force the state to use its own personnel and budget to carry out those duties.
A sanctuary law can therefore be lawful in one section and unconstitutional in another.
A provision saying local police will not voluntarily participate may survive.
A provision ordering private businesses to warn targets about upcoming federal operations may face a much harder challenge.
A law preventing federal officers from entering certain public spaces may be tested under intergovernmental-immunity and preemption doctrines.
That complexity is why the administration is filing lawsuits.
If the answer were as simple as “sanctuary policies are federal crimes,” prosecutors would not need twenty civil cases to determine which provisions courts will allow.
WHY SUPPORTERS WANT ARRESTS
The political demand grows from real frustration.
ICE identifies people in local jails who may be removable, including some accused or convicted of serious crimes.
When a jurisdiction refuses a detainer, agents may need to locate the person later in the community.
That operation can require more officers and create risk for neighbors, agents and the target.
Homan calls additional people encountered during those operations “collateral arrests.”
He argues that sanctuary policies do not prevent immigration enforcement. They push it out of controlled jail environments and into public spaces.
Supporters see mayors announcing noncooperation and conclude that elected officials value undocumented immigrants over public safety.
High-profile crimes intensify that anger.
Each case involving a person previously released despite an ICE request becomes evidence in the political argument, even when the city acted within existing law.
For those voters, arresting a mayor would send a message that federal immigration law cannot be ignored.
The Constitution requires more than a message.
It requires an offense.
WHY CRITICS SEE A CONSTITUTIONAL CRISIS
Critics fear the administration will use criminal investigations to punish protected disagreement.
A mayor who can be subpoenaed or arrested for declining voluntary cooperation may no longer possess meaningful local authority.
City officials may abandon lawful policies because defending them is financially and personally dangerous.
The threat could turn federal prosecutors into instruments for forcing political compliance.
Recent enforcement history adds to that concern.
A Reuters investigation found the Justice Department filed hundreds of assault or obstruction charges connected to immigration protests, while a striking share of completed cases were later dropped.
Dismissed cases do not prove every arrest was wrongful.
They show the danger of charging first in a politically intense environment and testing the evidence later.
An arrest itself can destroy a reputation, drain finances and remove an official from public life even when the case ultimately fails.
That is why the probable-cause requirement matters most when the target is unpopular with the administration.
THE QUESTION THAT CHANGES EVERYTHING
Did the official refuse to help?
Or did the official actively interfere?
That question determines almost everything.
A mayor cannot order federal agents out of the United States.
A mayor cannot hide a named target, destroy evidence or physically obstruct a lawful arrest.
A mayor can often decide that city police will not perform federal civil-immigration work.
A mayor can criticize ICE.
A mayor can tell residents to demand a judicial warrant before agents enter a private home.
A mayor can challenge federal policy in court.
The line may become difficult when officials coordinate warnings, restrict access to facilities or direct employees to withhold information.
Those cases require facts, not slogans.
Tom Homan can promise consequences.
The Justice Department can investigate.
Grand juries can subpoena records.
Courts must decide where local autonomy ends and criminal obstruction begins.
Until evidence shows a particular mayor crossed that line, “arrest sanctuary mayors” remains a political demand rather than a legal conclusion.
The controversy is not really about whether federal immigration law applies inside sanctuary cities.
It does.
The hidden question is who must help enforce it.

Washington may send ICE anywhere federal law permits.
The Constitution does not automatically require the mayor to hold the door open.
