"After the unrest at the U.S. Capitol on January 6, 2021, sources reported that current and former military
service members were among the participants in the unrest. These reports prompted several Members of
Congress to ask the Department of Defense to investigate service members’ participation and take
disciplinary action. The military is investigating whether any active-duty service members participated in
the unrest, and the Joint Chiefs of Staff issued a memorandum condemning the “violent riot” and actions
“that were inconsistent with the rule of law.”
This Legal Sidebar examines potential violations of the Uniform Code of Military Justice (UCMJ),
codified in Title 10 of the U.S. Code, those service members may have committed. The Sidebar begins by
discussing which current and former service members are subject to the UCMJ. It then examines offenses
under the UCMJ that current or former service members may have committed on January 6, 2021,
including potential sentences for each offense. It concludes with several considerations for Congress.

Capitol Unrest, Legislative Response, and the Bill of Attainder Clause
"On January 6, 2021, a crowd gathered on the U.S. Capitol grounds, breached police barriers, entered and
occupied portions of the Capitol building, and clashed with law enforcement. The incident resulted in at
least five deaths, dozens of injuries, and damage to federal property. Members of Congress and the Vice
President, who were counting electoral votes for the 2020 presidential election, were forced to evacuate in
response to the unrest. Following the incident, some Members of Congress and other commentators have
called for accountability for the individuals directly involved in the incident, as well as for others,
potentially including elected officials, who may have incited or supported the unrest.
Many of those calls for accountability raise complex legal issues. As a recent CRS Legal Sidebar
explains, the incident may implicate numerous provisions of existing criminal law. In addition, on January
13, 2021, the House of Representatives impeached President Donald Trump for incitement of insurrection
based on the events of January 6. Lawmakers and commentators have also explored imposing liability
under other legal authorities, including by passing new legislation or seeking to bar certain individuals
from holding office under Section 3 of the Fourteenth Amendment.
This Legal Sidebar addresses one of the more novel issues that these proposals may raise. The Bill of
Attainder Clause prohibits Congress from enacting legislation that inflicts punishment on an individual
basis without a judicial trial. This Sidebar provides an overview of the Bill of Attainder Clause and
presents certain related legal considerations for Congress as the legislature responds to the Capitol unrest..."
