President Donald Trump has repeatedly threatened to invoke the Insurrection Act of 1807 in response to protests against Immigration and Customs Enforcement operations, most recently in Minnesota in January 2026 following shootings involving federal agents and subsequent unrest. The administration has instead relied on National Guard deployments under separate authorities such as 10 U.S.C. 12406 to protect federal personnel and property during immigration enforcement surges. No formal invocation has occurred despite earlier considerations tied to border security and anti-deportation demonstrations in cities including Los Angeles and Chicago. Congressional proposals to limit presidential authority under the Act remain pending, while trader sentiment tracks the potential for escalated civil disorder or policy shifts that could trigger its use before year-end deadlines.
