This Day in Legal History: Aaron Burr Acquitted of Treason

On September 1, 1807, a jury in Richmond, Virginia acquitted Aaron Burr—the former Vice President of the United States—of treason, in what remains the only time such a high-ranking American official has ever been tried for that crime. The verdict was delivered in memorably grudging terms: the jury said Burr was “not proved to be guilty under this indictment by any evidence submitted to us.” Burr had allegedly conspired to carve an independent republic out of western territory, but he walked free.

The reason he walked free is one of the most important principles in American criminal law. The framers of the Constitution, remembering how English kings had used vague, elastic treason charges to destroy their political enemies, deliberately wrote the narrowest possible definition into Article III: treason against the United States consists only of levying war against them, or adhering to their enemies, and—crucially—no one can be convicted except on the testimony of two witnesses to the same overt act, or on confession in open court. Presiding over the trial was Chief Justice John Marshall, and Marshall enforced that definition strictly. He held that mere conspiracy, mere intention, mere assemblage of men was not enough—the government had to prove an actual overt act of levying war, with two witnesses. It couldn’t, and Burr was acquitted.

The significance of September 1, 1807 is layered. It was a dramatic clash between the branches: President Thomas Jefferson desperately wanted Burr convicted and worked behind the scenes to make it happen, while Marshall’s court insisted on rigorous proof and refused to bend to political pressure—even subpoenaing the president himself for documents. It cemented the idea that “treason” cannot be a catch-all for disloyalty, and that an independent judiciary must hold the line on proof even when a president demands a scalp. On a day featuring both a murder verdict and several tests of executive power, Burr’s acquittal is a fitting reminder that the highest function of a court is sometimes to say no.

A jury in Las Vegas has found Duane “Keffe D” Davis guilty of first-degree murder for orchestrating the 1996 killing of Tupac Shakur—closing, at last, one of the most notorious cold cases in American music history nearly thirty years after the fact. We’ve tracked this trial from jury selection through the defense’s remarkable “don’t believe my client” strategy, and now it’s over: after a weeks-long trial, the jury deliberated for under three hours before convicting. Prosecutors never claimed Davis pulled the trigger. Their theory, as the deputy district attorney put it in closing, was that “this was a case about gang retaliation and revenge”—that Davis provided the gun and ordered the attack, making him criminally responsible for the murder even though someone else fired the shots. And the evidence that convicted him was, essentially, Davis himself: the interviews, the podcasts, and the 2019 memoir in which he described his role in the killing. His own lawyer’s defense was to beg the jury not to credit those statements—to treat them as the lies of a braggart embellishing for money and street credibility. The jury didn’t buy it. The significance is a striking answer to the evidentiary question I flagged when this trial opened: yes, a man’s public boasts about a crime can be enough to convict him of it. Davis talked his way from “long-suspected” to “convicted murderer.” It’s a cautionary tale as old as the law itself—that the words you say to burnish your legend can become the words that put you in prison—and it brought a measure of accountability to a killing that went unpunished for three decades.

The legal war over mail-in voting grinds on: the Trump administration has asked the First Circuit Court of Appeals to lift the order still blocking parts of the president’s executive order overhauling how ballots are delivered. Recall the state of play. Last week, the Supreme Court, on its emergency docket, lifted one of two injunctions—letting some pieces of the order take effect—but pointedly did not rule on whether any of it is actually lawful, and the Postal Service’s role remained blocked nationwide. Now the administration is going back to the appeals court to try to clear that remaining block. Its arguments are largely practical: it says the lower court’s injunction was premature, issued before the Postal Service and other agencies had even finalized their plans, and that the injunction created an impossible situation—a “bifurcated” system where the order is blocked in the 23 states that sued but allowed everywhere else, which the government says is logistically unworkable. Meanwhile, there’s a new wrinkle: a whistleblower has reportedly claimed the Postal Service’s plan to implement the order could actually “derail” the midterms. The significance is that this is heading, almost inevitably, back to the Supreme Court—which still has not addressed the fundamental question of whether the president can restructure how Americans vote by mail. We are now roughly two months from the election, and the machinery of how ballots get delivered is being litigated in real time, court by court, on emergency timelines. The uncertainty itself is a problem: election administrators and voters need to know the rules, and right now the rules are moving.

And finally, a divided Supreme Court has cleared the way—for now—for construction of President Trump’s new White House ballroom to continue. In a 5-4 emergency ruling, the Court granted the administration’s request and blocked lower-court orders that would have paused the aboveground portion of the project. Some background: in 2025, the administration had the White House’s East Wing demolished—without notifying Congress—to make room for a planned 90,000-square-foot ballroom projected to cost $400 million or more, including an extensive underground component the administration says houses secure facilities. The National Trust for Historic Preservation sued, arguing the president had no authority to demolish part of the White House and build this on his own. The legal hook the Court used is a familiar one: standing. The majority said the Trust likely doesn’t have standing—the legal right to bring the suit in the first place—which is often how courts dispose of cases without confronting the underlying merits. And that’s the key caveat: the unsigned order does not decide whether Trump actually has the authority to build a massive ballroom without congressional approval. That question stays open as the litigation continues. The significance is twofold. Substantively, a president reshaping the White House itself, demolishing a historic wing without telling Congress, raises real questions about the limits of executive authority over federal property. Procedurally, this is once again the emergency docket letting the executive proceed on a threshold technicality—standing—while leaving the hard constitutional question for another day, if it’s ever answered at all. By the time the merits are sorted out, the ballroom may simply be built. Supreme Court lets Trump’s White House ballroom construction continue for now | ReutersCNBC · NBC News
