The first mistake most people make when an executive privilege assertion letter lands is treating it as a political press release. They scan for the headline, count the adjectives, and decide whether to cheer or jeer. That is exactly backward. The assertion letter is not a press release. It is a constitutional instrument, the closest thing the executive branch has to an affidavit explaining why it will not comply with a lawful demand for information. Read it that way, and it becomes a remarkable diagnostic tool. It tells you whether a president understands the office he holds, or merely wants the power without the limitations.

The second mistake is thinking the words "executive privilege" are magic. They are not. Saying them does not make a subpoena disappear. A letter that simply announces, "The President has directed me to assert executive privilege over the requested documents," is not a legal argument. It is a bureaucratic shrug. And if the matter goes to court, that shrug gets no deference.

I want to give you a better way to read these letters. Four questions. If the letter can answer all four, the system is working. If it cannot, the president who signed it has forgotten what the office is for.

The Power Is Real, but It Is Implied

Let's be clear at the outset: executive privilege is a genuine constitutional power. The words "executive privilege" appear nowhere in the Constitution, and that fact causes some people to dismiss the whole idea. They are wrong. The power is implied by the structure of Article II, which vests the executive power in a single president and charges him to take care that the laws be faithfully executed. It is also rooted in the plain logic of the office.

Alexander Hamilton put it in Federalist 70: "Decision, activity, secrecy, and despatch will generally characterize the proceedings of one man, in a much more eminent degree than the proceedings of any greater number." A president cannot receive candid advice if every memo, email, and private conversation is subject to immediate congressional disclosure. Advisors will speak in whispers. They will stop writing things down. The people will lose the benefit of honest counsel precisely when they need it most, during war, negotiation, and constitutional crisis.

George Washington understood this. In 1796, the House of Representatives demanded that he turn over papers related to the negotiation of the Jay Treaty. Washington refused. And he did not simply say no. He grounded the refusal in the treaty power itself: treaties are made by the president with the advice and consent of the Senate, not the House. The House had no constitutional role in treaty-making, and therefore had no right to the papers.

That is what a serious assertion looks like. It reasons from the Constitution, not from convenience. Washington did not claim a general right to hide whatever he wished from Congress. He drew a line around a specific constitutional function, treaty-making, and showed why disclosure to the House would undermine the president's ability to perform it.

But precisely because the privilege is implied rather than enumerated, the burden of justification falls on the executive. The president has to show why this particular withholding is necessary to preserve the functioning of the presidency. A real assertion is a scalpel. A blanket claim is a club.

What a Serious Assertion Letter Must Do

So what should we look for when an executive privilege assertion letter lands? The good ones share the same features. The bad ones share the opposite. There are four tests.

First, it must identify the privilege. "Executive privilege" is not one thing. It is a family of related protections. The two most common are the presidential communications privilege, which protects communications made in the course of presidential decision-making, and the deliberative process privilege, which protects pre-decisional, deliberative agency documents. The first is broader, more firmly rooted in Article II, and harder for Congress to overcome. The second is weaker and more easily pierced when Congress has a substantial need. A letter that lumps them together, or worse, simply says "executive privilege" without specifying which branch it invokes, is not making a legal argument. It is waving a flag. A serious letter says, in substance, these documents are presidential communications made in connection with official decision-making, and here is why they fall within the core of the privilege. That allows a court, and the public, to evaluate the claim on its merits.

Second, it must describe what is being withheld. The letter should identify categories of documents and explain why each category falls within the privilege. A serious letter does not say "all documents and communications related to the matter." That is the language of a cover-up, even when the underlying motive is innocent. The Constitution creates a presumption of transparency with respect to Congress's legitimate oversight functions. The burden is on the executive to overcome that presumption, item by item, not with a sentence but with a showing. A responsible White House counsel will write something like: The documents withheld include mental impressions and recommendations prepared for the President's decision on this subject, internal legal advice about the subject, and drafts of a message to Congress. These categories fall within the presidential communications privilege because their disclosure would inhibit the candid advice the President requires. That is not merely a formality. It is the executive respecting the rule of law by giving reasons.

Third, it must be the president's own assertion. The privilege belongs to the presidency, not to the staff. A senior advisor cannot invent it. The letter should state clearly that the president personally reviewed the matter and directed the assertion. If the letter is signed by a deputy assistant and never mentions the president's direct involvement, it is constitutionally empty. The Supreme Court has long recognized that the privilege is grounded in the president's need for candid advice, and it is the president who must exercise it. Eisenhower understood this. In 1954, during the Army-McCarthy hearings, he did not let a subordinate hide behind the word. He personally wrote a letter to the Secretary of Defense directing that certain officials not testify about internal executive communications. The power was exercised by the man who held it, not outsourced to a staffer in a hallway. That is the model.

Fourth, it must acknowledge the limits. The privilege is not absolute. In United States v. Nixon in 1974, the Supreme Court recognized a presumptive privilege for presidential communications but held that it must yield to a demonstrated, specific need in a criminal trial. "The privilege is not absolute," the Court said. A serious letter does not pretend otherwise. It acknowledges Congress's legitimate interests and offers to negotiate. It narrows the dispute rather than expanding it.

That last point is not weakness. It is the separation of powers working as designed. Congress has its own constitutional authority, legislation, oversight, the power of the purse, and impeachment. A president who treats Congress as a supplicant is not defending executive power; he is degrading the republic. A serious assertion letter respects Congress even while refusing a particular request. It says, in effect, here is what I cannot give you, here is why, and here is what I can offer instead. That is the conduct of a president who understands he is a trustee, not a monarch.

What a Weak Letter Reveals

Now consider the alternative. A weak assertion letter is a confession. It tells you that the executive either does not understand the privilege or does not respect it. The telltale signs are easy to spot.

A weak letter is vague. It asserts privilege over "all documents and communications" without identifying a single category. It cites no particular harm to the executive's decision-making. It uses the word "privilege" as if saying it three times makes a subpoena disappear.

A weak letter is signed by the wrong person. When the White House counsel writes, "I have been directed to assert executive privilege," but the president never appears in the document, the reader is entitled to ask whether this is the president's assertion, or whether the staff is hiding behind his title. The office belongs to the people. It cannot be invoked by a deputy in a hallway.

A weak letter offers no accommodation. It treats Congress as an enemy to be defeated rather than a coequal branch to be persuaded. That is not strength. It is the behavior of someone who fears the merits of his argument.

And a weak letter is a legal liability. If the matter goes to court, judges will read the letter line by line. A vague assertion is the legal equivalent of taking the witness stand and saying, "Because I said so." That does not win cases. It loses them.

The most important thing to understand is this: executive privilege is a shield for the office, not a cloak for misconduct. The moment a president invokes it to hide evidence of crime, personal embarrassment, or political inconvenience, he is no longer exercising executive privilege. He is asserting personal privilege, and the Constitution has no such thing. The Founders did not create a presidency to protect the man who holds it. They created it to protect the republic. A proper assertion letter reflects that distinction. A bad one erases it.

The Originalist Standard

Originalism is often caricatured as a mechanical enterprise: find the text, read it, done. But originalism is actually a discipline of humility. The president's powers are those the Constitution grants him, expressly or by necessary implication, and no more. Executive privilege survives originalist scrutiny because it is necessary to the functioning of the executive. It does not survive as a blank check.

So when I read an executive privilege assertion letter, I ask four questions. Does it identify the privilege? Does it identify the documents? Is it the president's own assertion? Does it acknowledge the limits? If the answer to any of those questions is no, the letter fails, not as a political document, but as a constitutional one.

The beauty of this standard is that it is party-blind. I have seen weak letters from administrations I otherwise support and strong ones from administrations I do not. That is how it should be. The Constitution is not a partisan instrument. It is a check on power, and the people who hold power will always be tempted to stretch it. The assertion letter is one of the few places where that temptation becomes visible in writing.

A wise president understands that secrecy, used properly, preserves the republic; used arbitrarily, it corrodes it. He does not hide behind the word. He explains it. He does not merely assert authority. He earns it. And he does not treat Congress as a nuisance. He treats it as a coequal branch whose legitimate functions the Constitution protects.

Read the Letter, Not the Headline

The next time an executive privilege assertion letter makes the news, do not read the headline. Read the letter. Ignore the adjectives and look at the structure. Is it a legal argument or a slogan? Does it reason from the Constitution or from convenience? Does it respect the office and the republic, or does it treat the presidency as a crown?

That document is a small but real test of whether we still have a government of laws and not of men. The power to keep secrets is necessary in a free republic. The power to assert that privilege arbitrarily is not. The difference is in the letter.

If it reads like an oath, the system is working. If it reads like a press release, it is not. And if it reads like "no," without reason, without limit, without accountability, then the president who signed it has forgotten what Washington understood: the privilege belongs to the office, not to the man.
