The Impeachment of Andrew Johnson When Congress Forgot the Constitution

Every schoolchild hears the same story. Andrew Johnson was a stubborn, racist president who stood in the way of noble Reconstruction, and the heroic Radical Republicans impeached him to protect the freedmen. The textbooks frame it as a righteous stand against a man who would have handed the South back to its old masters. That is the story they want you to believe. The real story is far more dangerous to liberty and far more instructive for our own time. Johnson was impeached because he dared to defy a law that was itself a flagrant violation of the Constitution. The Tenure of Office Act of 1867 forbade the President from removing any cabinet officer without the Senate's consent. A law passed by Congress, enforced by Congress, and then used by that same Congress to impeach the President who defied it. That is not justice. That is a legislative mugging dressed up in constitutional robes.

The Constitutional Question the Schools Skip

The Constitution says nothing about the Senate having a veto over presidential removals. Article II vests "the executive Power" in the President. It requires the Senate's advice and consent for appointments, but it says absolutely nothing about removals. The plain text, read honestly and originally, leaves that power with the President, who is constitutionally responsible for seeing that the laws are faithfully executed. You cannot hold a man responsible for execution if you strip him of the power to command his own subordinates. Alexander Hamilton made this clear in Federalist No. 77. The First Congress, the same Congress that included James Madison and other framers, confirmed it in 1789 after intense debate. They explicitly preserved the President's sole removal power, setting a precedent that held for seventy-eight years. That debate was settled law until the Radical Republicans decided they did not like the outcome.

The Tenure of Office Act was a naked attempt to subordinate the executive branch to the legislative. It was central planning of the worst kind, a committee of 535 people claiming the authority to micromanage the President's cabinet. Friedrich Hayek would have recognized the problem instantly: the arrogant pretense that a collective body could possess the dispersed knowledge needed to direct the executive's personnel decisions. Thomas Sowell would have spotted the disconnect between good intentions and disastrous consequences. The law was a trap, plain and simple, and the men who set it knew exactly what they were doing.

What Was Really at Stake

Johnson's defenders are often dismissed as apologists for the Old South, but that misses the constitutional principle entirely. Johnson was a Democrat from Tennessee who had remained loyal to the Union. He supported Lincoln's lenient Reconstruction plan, a plan designed to restore the Southern states quickly without punitive military occupation. The Radical Republicans wanted something else entirely: a wholesale restructuring of Southern society under military rule, directed from Washington. Their grievance against Johnson was not that he had committed a crime. It was that he disagreed with them on policy.

And so they passed a law specifically designed to trap him. The Tenure of Office Act protected cabinet members for the full term of the President who appointed them plus one month. Since Johnson had inherited Lincoln's entire cabinet, this meant he could not remove any of them without Senate approval. When Johnson finally dismissed Secretary of War Edwin Stanton, a Radical sympathizer who had been actively working against him from inside the administration, the House impeached him in three days. Eleven articles of impeachment. Nine of them related to the Stanton removal. None of them alleged anything that the Founders would have recognized as a "high Crime or Misdemeanor." The whole affair was a political hit job dressed up in legal language.

The Radicals controlled the House and they knew they had the votes. They did not care about due process or constitutional niceties. They wanted Johnson out, and they were willing to bend every rule to get him. This was not about justice or the rule of law. It was about power. It was about a legislative majority that believed it had the right to dictate every aspect of governance, including who served in the President's own cabinet. The impeachment was the weapon, and the Constitution was the casualty.

The Trial That Saved the Republic

The Senate trial lasted from March to May 1868. The Radicals controlled the chamber and the proceedings. They twisted procedural rules, pressured witnesses, and turned the event into a circus of partisan vitriol. Chief Justice Salmon Chase presided, but even his authority was constantly challenged by the Radical leadership. The atmosphere was toxic, and the outcome seemed certain. Everyone assumed Johnson would be convicted and removed.

Yet in the end, they fell one vote short of conviction. Seven Republican senators broke ranks and voted to acquit. Senator Edmund Ross of Kansas, the deciding vote, later said, "I almost literally looked down into my open grave" for his decision. He knew he was ending his political career, and he was right. He never held office again. But that single act of conscience preserved the independence of the executive branch. The Constitution was saved by men willing to lose everything for principle.

Those seven men were not Johnson supporters. They disagreed with his policies and disliked him personally. But they understood that the impeachment was a sham, that the law he had violated was itself unconstitutional, and that removing a President for political reasons would set a precedent that would haunt the republic forever. They exercised judgment over party loyalty. They chose the Constitution over their own careers. That is the kind of courage that is desperately lacking in our own era.

The Aftermath and the Modern Lesson

The Tenure of Office Act was partially repealed in 1887. In 1926, the Supreme Court in Myers v. United States effectively declared the whole premise unconstitutional, holding that the President's removal power is inherent in the executive power and cannot be conditioned by Congress. Chief Justice Taft wrote the opinion, and he cited that very First Congress debate from 1789 as authoritative. The Court finally said what should have been obvious from the start: the President must have control over his own cabinet.

But the damage was done. The precedent had been set: impeachment could be used as a weapon of political warfare, not just as a remedy for genuine constitutional crimes. The Radical Republicans established the principle, never written but always lurking, that a Congress can impeach a President for defying its will, even when that will is unconstitutional. Every modern impeachment driven by policy disagreement rather than actual high crimes is the ghost of that original sin. The same impulse to centralize power, to subordinate the executive to the legislative, to use the lever of the Constitution to crush a political opponent. The names change. The principle does not.

We see it today in the constant calls to impeach presidents for political disagreements. We see it in the erosion of the separation of powers as Congress tries to grab more and more control over the executive branch. The Johnson impeachment was the first shot in a war that has never really ended. It established the dangerous idea that impeachment is just another political tool, available whenever the opposition controls enough votes.

What This Means for Us Today

Johnson was no saint. His views on race were wrong and backward, and his approach to Reconstruction failed the freedmen in important ways. But the Constitution is not a reward for good behavior. It is a restraint on power, period. If we allow Congress to impeach a President for violating a law that Congress had no right to pass, we have surrendered the very separation of powers the Founders built. The Constitution was designed to protect liberty by dividing power and setting ambition against ambition. When one branch can use the impeachment power to destroy another for policy disagreements, that protection collapses.

The impeachment of Andrew Johnson was not about justice. It was about a legislature that forgot it was supposed to be one branch among three, not the master of all three. It was about the eternal temptation of the legislative branch to rule, and the eternal duty of the executive to resist, even at the cost of his own office. That is the forgotten angle of this history. And it matters more now than ever, as we watch the same patterns repeat themselves in our own time.

We need to recover the judgment of those seven Republican senators who put the Constitution above party. We need to remember that impeachment is a constitutional emergency brake, not a political cudgel. The Johnson case stands as a warning: when you use the Constitution as a weapon, you damage the very thing you claim to protect. The Radical Republicans thought they were saving the Union. Instead, they planted a time bomb that has been exploding ever since.
