Obstructing an official proceeding

Corruptly obstructing, influencing, or impeding an official proceeding is a felony under U.S. federal law. It was enacted as part of the Sarbanes–Oxley Act of 2002 in reaction to the Enron scandal, and closed a legal loophole on who could be charged with evidence tampering by defining the new crime very broadly.

This part of the Act later became known as a charge against defendants associated with the 2021 U.S. Capitol attack for attempting to obstruct that year's Electoral College vote count, as well as former President Donald Trump for broader alleged activities to obstruct the election. In June 2024, the Supreme Court ruled in Fischer v. United States that the statute could only be applied when the defendant impaired a physical document or object used in an official proceeding or attempted to do so, a higher bar for conviction than had actually been used in trials to that point.
