No president can legally pardon himself for a crime as severe as murder without facing extraordinary constitutional and practical barriers. While the presidential pardon power is broad under Article II of the Constitution, it explicitly applies only to federal crimes and excludes cases of impeachment.
A self-pardon for a federal homicide would immediately trigger impeachment proceedings in Congress, which is the only mechanism that can remove a president from office. Beyond impeachment, state-level prosecution for murder would proceed independently, since no federal pardon covers state crimes. This article examines the constitutional limits on pardon power, the distinction between federal and state jurisdiction, the unanswered legal question of self-pardons, and the practical checks Congress and the courts have available to constrain any attempt at self-immunity.

What Does the Presidential Pardon Power Actually Allow?
The Constitution grants the president broad power to “grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.” This language has been interpreted by courts to allow presidents to pardon anyone for any federal crime, commute sentences, and issue blanket pardons to groups of people. Presidents have used this power to pardon political allies (Richard Nixon’s aide H.R. Haldeman), family members (Joe Biden’s son Hunter), and even themselves nominally—though no sitting president has actually tested self-pardon in court.
The pardon power is one of the few presidential authorities that operates almost entirely outside judicial review; courts typically refuse to question the president’s exercise of it, treating it as an unreviewable political decision. However, the pardon power contains one explicit limit: it cannot be used “in Cases of Impeachment.” This means if a president is impeached, the president cannot pardon away the impeachment charges themselves. This is a structural constraint built into the Constitution to preserve Congress’s power to remove the president. The framers deliberately separated the pardon power from the impeachment power to ensure that a president facing removal could not simply pardon their way out of accountability to Congress.
Why Federal Crimes Are Separate From State Crimes
This distinction is critical: a presidential pardon covers only federal offenses—crimes prosecuted under federal law, tried in federal courts, and handled by federal prosecutors. Murder in New York State is a state crime, not a federal crime, regardless of where it occurs. Only in rare circumstances does a homicide become a federal crime (for example, if it occurred at a federal facility or involved federal officials in their official capacity). Someone shot on 5th Avenue in Manhattan would normally be prosecuted under New York State law, not federal law.
The federal pardon power has zero effect on state crimes. A president cannot pardon someone for a state crime any more than the president can pardon someone for violating New York State tax law or committing assault in California. Each state maintains its own pardoning authority, typically vested in the governor. This structural separation is fundamental to American federalism: the states retain independent power to prosecute and punish crimes within their borders, and the federal government’s pardon power does not override that authority. If a president were to shoot someone in New York, New York prosecutors could indict and try the case regardless of any federal pardon.
The Unresolved Question of Self-Pardon and Legal Precedent
No sitting president has ever tested whether they can legally pardon themselves, so the question remains unresolved in constitutional law. Legal scholars are divided. Some argue that the Constitution’s language (“the President…shall have Power to grant Reprieves and Pardons”) is absolute and includes self-pardon. Others contend that the principle that “no one should be a judge in their own case” (nemo iudex in causa sua) overrides a literal reading, or that self-pardon conflicts with the fundamental structure of the Constitution. In 2018, President Trump’s legal team asserted in a memo that the president could pardon himself, but this assertion was never tested in court and remains a matter of heated academic debate among constitutional lawyers.
The reason this question has never been litigated is that any attempt at self-pardon would immediately trigger impeachment before it could reach the courts. Congress would almost certainly vote to impeach a president who shot someone on 5th Avenue and then pardoned themselves. The House Judiciary Committee would likely move an impeachment resolution within days. Rather than allowing the self-pardon to stand, Congress would proceed directly to removal via impeachment and conviction in the Senate. This political reality means that self-pardon for murder would face a congressional veto before the judiciary ever had to rule on its legality.
Impeachment as the Practical Limit on Self-Pardon
The Constitution’s exclusion of impeachment cases from the pardon power is the decisive practical limit. If a president pardoned themselves for a federal murder, Congress could immediately impeach the president on the grounds of that very act—not just the underlying murder, but the abuse of power in issuing a self-pardon. Impeachment requires only a simple majority in the House; removal requires a two-thirds majority in the Senate. In the modern political environment, a president who committed murder and pardoned themselves would face near-certain impeachment in any Congress.
Once impeached, the pardon becomes irrelevant. A presidential pardon has no effect on impeachment proceedings; the Senate’s power to remove the president is completely independent of any pardon the president issued. Even if the president pardoned themselves for the underlying federal crime, they cannot pardon themselves for the impeachable offense of abusing the pardon power or the offense of the underlying crime as an impeachable matter. This creates a logical trap: self-pardon triggers impeachment, and impeachment places the president beyond the reach of the pardon power.
The Immunity Fallacy and Constitutional Checks
A related but distinct question concerns presidential immunity during a term in office. Some legal interpretations suggest that a sitting president cannot be criminally prosecuted in federal court—a doctrine that some expanded after the Supreme Court’s 2024 decision on presidential immunity. However, this immunity doctrine does not prevent impeachment, which is a separate political process. A president with criminal immunity from prosecution can still be impeached and removed by Congress.
Moreover, presidential immunity during a term typically ends once the president leaves office, at which point criminal prosecution can resume. The self-pardon question intersects with immunity doctrine in confusing ways. Even if a president had immunity from prosecution while in office, that does not require granting themselves a pardon. And if they did pardon themselves to create an additional legal barrier for after they leave office, that pardon could potentially be challenged or overturned by Congress, the courts, or a successor administration. No clear precedent exists on whether a pardon issued under questionable circumstances—such as a self-pardon for murder—would hold up in court if challenged.
State-Level Prosecution and the Limits of Federal Power
As noted, a murder committed in New York would be prosecuted by New York State, and New York’s governor is the only official with authority to pardon state crimes. A sitting U.S. president has no power to stop a state prosecution or pardon a state conviction. During a presidency, a sitting president generally has immunity from state criminal prosecution (a doctrine the Supreme Court reinforced), but this immunity is temporary and ends when the presidency ends. Once out of office, the former president can be prosecuted by any state.
In the hypothetical scenario of a president shooting someone on 5th Avenue, the state of New York could proceed with a state murder prosecution as soon as the president leaves office. No federal pardon protects against this. The only way to prevent state prosecution would be for New York’s governor to issue a pardon—an extremely unlikely political outcome if the act in question was a high-profile murder. Additionally, various state crimes could pile on: assault, reckless endangerment, and weapons charges. The federal pardon power is irrelevant to all of them.
Future Constitutional Clarity and Reform Proposals
Given the potential for abuse, there is ongoing discussion among constitutional scholars and lawmakers about whether the Constitution should be amended or clarified to explicitly prohibit self-pardon. Some legal experts have proposed legislation (though it would need to survive constitutional challenge) that would restrict self-pardon explicitly. However, absent such amendment or legislation, the question technically remains open. The most likely scenario is that Congress would use impeachment as the check, making the legal question moot.
The practical lesson is that the pardon power, however broad, operates within a system of separated powers. No single branch can unilaterally override the Constitution or disable congressional oversight. Even if a president attempted a self-pardon for a federal crime, Congress, the states, and the judiciary all have mechanisms to resist and constrain that power. The “broad” pardon power is broad within limits, not beyond them.
Conclusion
A president cannot legally pardon themselves for shooting someone on 5th Avenue without triggering impeachment and federal criminal charges, and they cannot pardon themselves for the state crime of murder at all. The pardon power is limited by the text of the Constitution (it excludes impeachment cases), by federalism (it does not extend to state crimes), by the separation of powers (Congress can impeach), and by the rule of law principle that no person is a judge in their own case.
While the precise constitutionality of self-pardon remains unresolved in the courts, the practical political and legal barriers are formidable. The key takeaway is that presidential power, even at its broadest, does not create absolute immunity or remove the president from accountability to the other branches of government or the states. The Constitution’s structure—with its explicit carve-out for impeachment, its federalist division of prosecutorial power, and its checks and balances—ensures that no single official, not even the president, can pardon their way out of serious criminal accountability.
