Immigrants' Rights
Barbara v. Donald J. Trump
President Trump is attempting to undermine the promise of birthright citizenship to children born on U.S. soil. But the ACLU and partners are fighting to protect the rights of citizens that are plainly stated in the Constitution, federal statute, and reaffirmed by the Supreme Court for more than a century. We’re arguing against the Trump administration in the Supreme Court and are confident we will win.

Sierra Club v. Trump — Challenge to Trump’s National Emergency Declaration to Construct a Border Wall
In February 2019, the ACLU filed a lawsuit challenging President Trump’s emergency powers declaration to secure funds to build a wall along the southern border. The lawsuit was filed on behalf of the Sierra Club and the Southern Border Communities Coalition. The lawsuit argues that the president is usurping Congress’s appropriations power and threatening the clearly defined separation of powers inscribed in the Constitution. On January 20, 2021, President Biden halted further border wall construction. Litigation in this and subsequent related challenges has been paused or deadlines extended while the ACLU’s clients and the Biden administration determine next steps.

Carvajal-Muñoz v. Ravencamp
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.
