The government cannot ban people from taxpayer-funded vice presidential events in retaliation for their constitutionally protected speech.

On April 11, 2025, the ACLU and ACLU of Maine filed a lawsuit on behalf of two human rights advocates who, because of an executive order signed by President Trump, have been forced to stop humanitarian work with the International Criminal Court.

This lawsuit seeks to use several tools, including a state civil rights act, to hold federal immigration agents accountable for violating the rights of a Portland resident who held a lawful visa. In January 2026, federal immigration officers descended on Maine as part of what the federal government has called “Operation Catch the Day.” The federal government claimed the operation targeted “the worst of the worst criminal aliens,” yet in fact it targeted many people who had committed no crimes. Among them was our client, Juan Sebastián Carvajal-Muñoz, a Portland-based civil engineer with a valid visa, who was seized by federal agents.   With the help of the ACLU and other law firms, Mr. Carvajal-Muñoz filed suit to hold the federal agents accountable. This case has significant implications: it could confirm that state laws can authorize individuals to hold federal officials accountable for violating rights protected by the U.S. Constitution.

Representing the ACLU of Maine, the ACLU Voting Rights Project and the ACLU of Maine filed an amicus brief in a federal lawsuit over the federal government’s demand that Maine turn over its entire voter registration rolls, including with voters’ sensitive personal data such as drivers’ license numbers and partial social security numbers.
