Montana AG Investigating Helena for Potential Sanctuary City Violations

City officials passed a resolution opposing federal immigration enforcement, raising concerns over state's sanctuary city ban.

Published on Feb. 12, 2026

Montana's Republican Attorney General Austin Knudsen announced an investigation into the City of Helena for potential violations of the state's sanctuary city ban. This comes after Helena city officials passed a resolution opposing federal immigration enforcement actions, which Knudsen claims violates a 2021 state law banning sanctuary cities.

Why it matters

The investigation highlights the ongoing tensions between local and state governments over immigration enforcement policies, with Republican-led states seeking to limit so-called "sanctuary" policies in cities and counties. This case could set a precedent for how the sanctuary city ban is interpreted and enforced in Montana.

The details

In 2021, the Montana legislature passed House Bill 200, which prohibits local governments from enacting policies that limit cooperation with federal immigration enforcement. The City of Helena recently passed a resolution stating the city will not assist with federal immigration enforcement actions unless required by law. Attorney General Knudsen claims this resolution violates the state's sanctuary city ban and has launched an investigation into the city's actions.
