On Monday, FBI agents searched Donald Trump’s residence at Mar-a-Lago in Florida. By Friday, a federal judge had unsealed the search warrant and an inventory of material seized from the property, showing that investigators removed boxes containing documents marked at several levels of classification. The warrant indicated that investigators were examining possible violations of federal laws concerning government records, obstruction and information relating to national defence.
Trump has described the search as politically motivated and an unprecedented weaponisation of law enforcement against a former president. Many Republican politicians have responded similarly, attacking the FBI and Department of Justice and arguing that institutions controlled by the current administration are being used against Joe Biden’s most important potential political opponent.
The Justice Department has said relatively little publicly about the underlying investigation, although Attorney-General Merrick Garland confirmed that he personally approved the decision to seek the warrant and defended the department’s procedures. The warrant itself was authorised by a federal magistrate judge after investigators presented evidence establishing probable cause.
There is still a great deal we do not know. A search warrant is not a conviction. The presence of documents at Mar-a-Lago does not by itself establish every element of a criminal offence, and investigators still have to determine the circumstances under which records were retained, how they were handled and whether any eventual prosecution is justified. Trump and his lawyers will have opportunities to challenge allegations if charges are ever brought.
That uncertainty matters because criminal investigations should not become political verdicts delivered before courts have considered evidence.
But the search already raises a much larger democratic problem regardless of the eventual legal outcome. How should a political system apply criminal law to somebody who has previously held its highest office and may seek that office again?
There are two principles that seem obviously correct until they collide.
The first is equality before the law. Former presidents cannot receive immunity from ordinary legal obligations simply because prosecuting them would be politically controversial. If holding high office makes someone effectively impossible to investigate afterwards, political power becomes a form of legal protection. That creates precisely the hierarchy liberal legal systems are supposed to prevent.
The second principle is that criminal law should never become a routine instrument for defeating political opponents. Democracies become extremely dangerous when governments can remove competitors through prosecutors rather than elections. Authoritarian states regularly preserve the appearance of legality by charging opposition leaders with crimes, obtaining convictions through institutions they control and then insisting that the matter is merely law enforcement.
Both principles are essential.
That is what makes the Trump investigation difficult institutionally even before we know whether the allegations are ultimately substantiated.
The answer cannot be “never investigate political leaders”, because that would create impunity. It also cannot be “political status is irrelevant”, because the political consequences of law enforcement against a former president plainly differ from those of an ordinary criminal investigation.
The standard therefore has to be something closer to this: political leaders should remain fully subject to law, but investigations involving them should operate under unusually strong evidentiary, procedural and transparency safeguards precisely because the potential for both abuse and public distrust is unusually high.
This is not special legal treatment in the sense of lowering accountability.
If anything, it should require greater institutional discipline.
The Mar-a-Lago search illustrates some of those safeguards. The FBI did not simply decide to enter Trump’s residence. Federal investigators had to obtain a search warrant from a judge. That requires presenting evidence establishing probable cause that evidence of a crime will be found in the location being searched.
Judicial authorisation does not prove the investigation is correct.
Judges can make mistakes.
Investigators can present incomplete information.
Institutions are operated by humans.
But requiring another institution to review the executive branch’s request creates a check against unilateral action.
This is what separation of powers is supposed to accomplish in practice. It does not guarantee perfect decisions. It increases the number of independent actors whose agreement is required before coercive state power can be exercised.
Institutional legitimacy therefore comes partly from procedure rather than outcome.
People naturally judge institutions according to whether they like the result. Trump supporters may distrust the search because it targets Trump. Trump opponents may assume it is justified because they already believe Trump behaves unlawfully.
Neither reaction is a reliable legal standard.
The more useful questions are procedural. Was there sufficient evidence for probable cause? Did investigators follow the same statutory framework they would apply elsewhere? Was the warrant appropriately limited? Will evidence eventually be tested through an adversarial legal process? Can courts operate independently from political pressure?
Those questions remain useful regardless of who is being investigated.
This is another version of the institutional test I have returned to repeatedly this year: would I support the rule if my opponent controlled the institution using it?
Democrats who support investigating Trump should ask whether they would accept the same legal standard applied to a former Democratic president.
Republicans attacking the search should ask whether they would genuinely believe a former Democratic president should be immune from investigation after retaining sensitive government records.
The identities should be removable from the principle.
If the principle changes when the politician changes, it probably was not a principle.
There is also a distinction between political motivation and political consequence that needs to be preserved. An investigation can have enormous political consequences without having been initiated for political reasons. Conversely, officials can follow superficially correct procedures while still possessing improper motives.
We therefore cannot infer motivation simply from consequence.
Trump may benefit politically from presenting the search as persecution. His supporters may become more mobilised. Republican politicians may rally around him. That does not prove investigators intended those effects.
Similarly, the Justice Department insisting that it follows ordinary procedures does not automatically establish complete institutional neutrality.
Evidence matters.
This sounds obvious, but polarised politics reverses the sequence. People decide which institution they trust and then interpret evidence through that prior belief.
The FBI provides a particularly interesting example because American conservatives and liberals have changed their attitudes towards federal law enforcement repeatedly depending on context. Institutions once strongly associated with law-and-order conservatism can suddenly become targets of Republican distrust when investigating a Republican leader.
The reverse can happen on the left when law-enforcement institutions produce outcomes progressives oppose.
Institutional trust therefore risks becoming conditional on partisan alignment.
That is extremely dangerous.
A democracy cannot function if half the country trusts courts, police, election officials and intelligence agencies only while those institutions produce outcomes favourable to its party.
Institutions need enough independence that they occasionally disappoint everyone.
In fact, an institution that never produces an outcome contrary to the interests of the political coalition controlling government should probably attract suspicion.
Independence creates politically inconvenient results.
That is partly its purpose.
This is also why attacks on the legitimacy of institutions should require more evidence than disagreement with their decisions. The FBI can abuse power. The Justice Department can become politicised. American history contains plenty of examples demonstrating that law-enforcement institutions do not deserve blind trust.
J. Edgar Hoover’s FBI surveilled political activists and abused investigative authority. COINTELPRO targeted civil-rights organisations and political movements. National-security institutions have repeatedly exceeded legitimate boundaries.
Institutional scepticism is therefore healthy.
Institutional nihilism is different.
Scepticism says: show me the evidence that this action was justified.
Nihilism says: the institution acted against my side, therefore the institution itself is illegitimate.
The first creates accountability.
The second makes accountability impossible because no institution remains capable of delivering an accepted answer.
This connects directly to the January 6 hearings I wrote about in June. Trump’s political strategy after the 2020 election relied partly on persuading supporters that institutions producing unfavourable outcomes could not be trusted. Election officials certified Biden’s victory, so the election system was corrupt. Courts rejected challenges, so courts were unwilling to examine fraud. Republican officials defended results, so they were disloyal.
The Mar-a-Lago investigation risks extending the same structure into criminal justice.
If the FBI investigates Trump, the FBI is corrupt.
If prosecutors eventually charge him, prosecutors are political.
If a court rules against him, the court may then become part of the same alleged persecution.
At some point, a political movement can construct a worldview in which no institution possesses enough independent legitimacy to constrain its leader.
That is a dangerous relationship between leader and state.
It turns institutional accountability into personal loyalty.
But Trump’s opponents should be careful not to create the mirror image. If every investigation is automatically assumed legitimate because the target is Trump, institutional procedure becomes secondary to the desired political result.
That would undermine exactly the rule-of-law principle they claim to defend.
The correct position has to be less emotionally satisfying.
Wait for evidence.
Demand procedural integrity.
Apply consistent standards.
Allow courts to distinguish allegations from crimes.
This is slow.
That is often the point of legal process.
Politics wants immediate conclusions because elections and news cycles move quickly. Law is supposed to move more deliberately because the state possesses coercive powers that can destroy liberty, property and reputation.
The tension becomes particularly severe when the person being investigated may run for president again.
Trump remains the dominant figure in the Republican Party and is widely expected to consider another presidential campaign in 2024. Any prosecution could therefore alter the next election.
That fact cannot automatically prevent prosecution.
Otherwise announcing a presidential candidacy could become a form of legal immunity.
A politician facing investigation could simply declare themselves a candidate and argue that any subsequent law-enforcement action constitutes electoral interference.
That incentive would be absurd.
But timing still matters.
Prosecutors need to recognise that actions taken near elections can affect democratic competition even when legally justified. The Justice Department has internal norms intended partly to prevent law enforcement from unnecessarily influencing elections.
Again, there is no perfect solution.
Delay too long and powerful politicians receive privileges unavailable to ordinary citizens.
Move too aggressively and legitimate law enforcement can appear indistinguishable from political intervention.
This is why institutional credibility accumulated before the crisis becomes so valuable.
A Justice Department broadly trusted as independent possesses more room to investigate powerful politicians without destabilising politics.
A department perceived as partisan has much less.
Trust is therefore a form of institutional capital.
Governments cannot suddenly manufacture it when they need to make a controversial decision.
They accumulate it through years of consistent procedure.
That makes appointments, prosecutorial independence and restraint during ordinary cases politically important even when nobody is paying attention.
Institutions prepare for extraordinary cases by behaving credibly during boring ones.
The classified-document issue itself raises another principle: public officials do not own the state.
Presidential records belong within legal and archival systems rather than becoming personal property simply because a president created or received them while in office.
This distinction between office and officeholder is fundamental to impersonal government.
A president temporarily exercises enormous authority.
The authority belongs to the presidency.
Government documents belong to the state.
Military information belongs to institutions.
The White House belongs to the public.
The person eventually leaves.
This is the same distinction I discussed after the January 6 hearings. Democratic office is temporary because the institution exists independently of whoever currently occupies it.
Personalised political systems blur that boundary.
The leader begins treating state resources, state information and state institutions as extensions of themselves.
That is one reason rules surrounding presidential records can have constitutional importance far beyond filing procedures.
Archives sound bureaucratic.
Bureaucracy is how states preserve the distinction between public authority and private ownership.
Max Weber described modern bureaucracy partly through this separation: officials occupy offices governed by impersonal rules rather than personally owning the powers attached to those offices.
That principle can sound abstract until a dispute emerges over whether government records leave with the government or the individual.
Institutionalisation often lives inside administrative details.
There is also a national-security dimension, although we should be cautious because the exact contents and sensitivity of seized documents remain incompletely known. The inventory indicates material bearing classification markings at several levels.
Classification itself does not automatically prove criminal conduct, and presidents possess unusually broad authority concerning classified information while in office. The legal questions surrounding declassification, retention and national-defence information are more complicated than simply asking whether a folder had a particular marking.
That complexity is another reason political commentary should not outrun the investigation.
The strongest institutional argument does not require us to decide Trump’s criminal liability today.
It requires recognising that sensitive government information needs rules independent of the personal preferences of former officials.
If those rules were violated, there should be consequences proportionate to the violation.
If investigators overreached, there should be consequences for that too.
Rule of law cuts in both directions.
Perhaps this is the most difficult thing about genuinely institutional politics.
You do not know in advance which side the institution will constrain.
That is why everyone is tempted to weaken institutions when they become inconvenient.
Presidents dislike independent prosecutors when they are investigated.
Legislatures dislike courts when laws are overturned.
Political parties dislike election officials when results go against them.
Governments dislike journalists when scandals are exposed.
Yet the same politician may desperately need those institutions later when their opponent controls government.
Institutional restraint is therefore a long-term bargain against short-term incentives.
I accept constraints on my power today because I want those constraints applied to you tomorrow.
This is the logic behind constitutional government.
Trump’s political career repeatedly tests that bargain because he interprets institutions in unusually personal terms. Officials are loyal or disloyal. Investigations are attacks. Electoral defeats are illegitimate.
His opponents risk reinforcing that personalisation if they respond by treating every institution confronting Trump as automatically virtuous.
The objective should be the opposite.
Depersonalise the entire process.
Donald Trump should neither be above the law nor beneath a harsher version of it.
He should be subject to it.
That sounds almost banal.
Achieving it when the person involved is a former president, possible future candidate and central figure in an intensely polarised political movement is extraordinarily difficult.
The FBI search this week therefore should feel both normal and exceptional.
Normal because former presidents remain citizens subject to legal process.
Exceptional because coercive state action against a former president deserves unusually careful scrutiny.
A healthy democracy needs to be capable of holding both ideas simultaneously.
If America decides former presidents are too politically important to investigate, it creates an elite above ordinary accountability.
If it decides criminal investigation is simply another acceptable instrument of partisan competition, it creates something equally dangerous.
The line between those outcomes is procedure.
Evidence.
Independent review.
Consistent standards.
And enough patience to allow the facts to become clearer before deciding which political story we want them to prove.
The FBI entered Mar-a-Lago on Monday.
Everyone immediately began arguing about what the search means.
Perhaps the most important democratic discipline now is admitting that we do not know yet.
Rule of law is not demonstrated by how quickly the public reaches a verdict.
Sometimes it is demonstrated by how long institutions are willing to wait before one becomes justified.
