  • One year ago, thousands of Coloradans marched in a historic display of resistance. At the ACLU of Colorado we carried that spirit throughout the year, fighting on many fronts for civil liberties. We won’t stop now.

  • By canceling DACA, Trump has put 800,000 young people at risk of losing their jobs and being deported from the only country they know as home. Passing the bipartisan Dream Act would protect them. We asked four Dreamers why the Dream Act is important to them and their future.

  • James Fisher spoke at the ACLU of Colorado Bill of Rights Dinner about how he and the ACLU are working together to stop the criminalization of poverty for the thousands of Coloradans who are trapped in debtors’ prisons.

  • Our membership has quadrupled in the last six months, making it possible to do more than ever to protect civil rights and civil liberties in Colorado. Thank you to all our new members, supporters, and donors, and the ones who’ve been with us for years.

End Immigration Detainers

The ACLU of Colorado successfully convinced all sheriffs in Colorado to stop holding people in jail on detainer requests from federal Immigration and Customs Enforcement.

Immigration detainers (also called “ICE detainers” or “ICE holds”) are routinely issued by federal Immigration and Customs Enforcement (“ICE”). They ask sheriffs to continue imprisoning a person for up to five days past the time when the person would otherwise be released, so that ICE can decide whether to take that person into federal custody for a possible immigration violation. Deportation proceedings are civil, not criminal, cases. Remaining in the United States in violation of federal immigration laws is not a crime.

After months of ACLU of Colorado advocacy with the sheriffs, Colorado became the first state in the country in which all county jailers now reject detainer requests from ICE. Read our press release.
