In the winter of 2016, the name of an obscure 1799 federal statute suddenly appeared in classified intelligence summaries, Justice Department deliberations, and eventually the national news cycle. The Logan Act — a law that had sat essentially dormant for more than two centuries, that had produced a single indictment in its entire history and zero criminal convictions — was being discussed at the highest levels of the incoming administration's transition period as a potential basis for investigating Michael Flynn, the retired general who had been named as Donald Trump's national security adviser.
For most Americans encountering the Logan Act for the first time, the question was reasonable: if this law is so important, why had no one ever actually been prosecuted under it? The answer, it turns out, reveals something important not just about the Flynn case but about how prosecutorial power is exercised in Washington — and why laws that cannot survive a serious constitutional challenge are sometimes most useful precisely because they never go to trial.
What the Logan Act Actually Says
The law was passed in January 1799, during the quasi-war with France, and was named after Dr. George Logan, a Pennsylvania Quaker who had traveled to France without authorization and conducted private negotiations with the Directory in an attempt to ease tensions between the two countries. Congress, outraged at the presumption, passed a statute making it a federal crime for any American citizen "without authority of the United States" to correspond with a foreign government "with intent to influence the measures or conduct of any foreign government" in relation to a dispute with the United States.
The penalty was originally up to three years in prison. Modern versions of the statute carry similar penalties. The law has been on the books continuously since 1799. In that span of 225-plus years, it has generated exactly one indictment — a Kentucky farmer named Francis Flournoy in 1803, who was accused of writing a newspaper article advocating the formation of a French-allied republic in the western United States. He was never tried. No one has ever been convicted under the Logan Act. Not once.
This is not because private citizens have refrained from conducting unauthorized foreign diplomacy. Jesse Jackson negotiated with foreign governments for the release of American hostages. Jimmy Carter has conducted extensive private diplomacy with foreign leaders throughout his post-presidency. Nancy Pelosi flew to Syria in 2007 to meet with Bashar al-Assad over the explicit objections of the George W. Bush administration. Ted Kennedy, according to documents later unearthed from Soviet archives, allegedly sought to coordinate political strategy with the Kremlin during the 1984 presidential campaign. None of these individuals faced Logan Act scrutiny of any consequence.
The Flynn Episode and What It Exposed
The Flynn case brought the Logan Act into uncomfortable focus. Flynn, during the presidential transition period between the November 2016 election and the January 2017 inauguration, spoke by phone with Russian Ambassador Sergey Kislyak. These conversations — the content of which was captured by routine intelligence surveillance of the Russian ambassador — were later characterized by some officials as potentially implicating the Logan Act, on the theory that Flynn was conducting unauthorized diplomacy with a foreign government.
The argument was, to put it charitably, a stretch. Presidential transition teams routinely communicate with foreign governments. The entire purpose of a transition period is to prepare the incoming administration to govern, which necessarily involves preliminary contact with foreign counterparts. The notion that a designated national security adviser communicating with a foreign ambassador during a presidential transition violates a law against unauthorized private citizens conducting foreign policy is an interpretation that strains the statute beyond recognition.
What made the episode particularly revealing was the internal deliberation it exposed. Declassified documents from the Flynn investigation showed that senior FBI and Justice Department officials debated whether the Logan Act provided a legitimate predicate for the investigation, with at least some officials apparently recognizing that it was constitutionally and legally dubious. The law was not ultimately used to charge Flynn — he was instead charged with making false statements to federal investigators — but its invocation at the investigative stage served a purpose: it provided a legal-sounding rationale for continued scrutiny of a political opponent at a moment when other justifications were thin.
A Law the First Amendment Should Have Buried
The constitutional problems with the Logan Act are substantial and have been recognized by legal scholars across the ideological spectrum. The most obvious is the First Amendment. The statute criminalizes speech — specifically, verbal or written communication with a foreign government aimed at influencing its conduct. The Supreme Court has made clear that political speech, including speech on matters of foreign policy, receives the highest constitutional protection. A law that makes it a federal crime to express certain political views to foreign officials sits in extraordinarily uncomfortable constitutional territory.
Due process presents an equally serious problem. The phrase "without authority of the United States" is undefined in the statute. Who grants such authority? The President? Congress? Some combination? The ambiguity is not incidental — it is structural, and it means that the law provides no clear notice of what conduct is prohibited. A criminal statute that does not give citizens fair warning of what it forbids is constitutionally infirm under the void-for-vagueness doctrine, regardless of its political convenience.
The strongest defense of the Logan Act's continued existence is that it serves as a deterrent — that even an unenforceable law sends a normative signal about the appropriate role of private citizens in foreign policy. This argument has a certain institutional logic to it. Unauthorized back-channel diplomacy can genuinely complicate official foreign policy, create confusion about American positions, and undermine the President's constitutional authority to conduct foreign relations.
But a deterrent that operates by threatening prosecution under an unconstitutional statute is not a legitimate legal tool — it is intimidation. And the selective pattern of that intimidation is impossible to ignore. The Logan Act is invoked, or threatened, or floated as an investigative predicate, almost exclusively against figures on the political right. The asymmetry is not accidental. It reflects a prosecutorial culture in which legal theories are evaluated less for their doctrinal validity than for their political utility.
The Broader Lesson
The Logan Act's persistence in American law offers a useful window into how the administrative and prosecutorial state operates. Laws that are constitutionally dubious, practically unenforceable, and historically unused do not survive for 225 years by accident. They survive because they are useful — not as tools of actual prosecution, but as instruments of leverage, investigation, and intimidation. The mere threat of a Logan Act referral, or the inclusion of the statute in an investigative predicate, creates legal jeopardy and public suspicion without requiring the government to actually test the law's constitutionality in front of a jury.
This is precisely the kind of prosecutorial architecture that the rule of law is supposed to prevent. A legal system in which the government can credibly threaten prosecution under a law it knows it cannot win is a system that has substituted political power for legal principle. The solution is not complicated: Congress should repeal the Logan Act, or the Supreme Court should strike it down. Either outcome would be constitutionally appropriate and institutionally honest.
What is not appropriate is continuing to let a 225-year-old zombie statute shuffle through Washington, occasionally biting conservatives who have the temerity to talk to foreign officials, while the political class that wields it faces no accountability for doing exactly the same thing.
A law that has never convicted anyone in two centuries is not protecting the republic — it is protecting the people who get to decide when to wave it around.
