The American Civil Liberties Union, New York Civil Liberties Union, ACLU of Texas, and Arnold & Porter filed a federal lawsuit July 24, 2020, on behalf of immigrants’ rights groups challenging President Trump’s order seeking to block people who are undocumented from being counted in the U.S. census.

The American Civil Liberties Union and partner organizations filed a lawsuit challenging Ohio’s practice of ‘purging’ or removing people who vote infrequently from its voting rolls, charging that it is in violation of the National Voter Registration Act (NVRA).

The American Civil Liberties Union and Disability Rights Advocates sued the New York State Board of Elections and Department of Motor Vehicles over online voter registration that is inaccessible to people with disabilities.

The American Civil Liberties Union, the ACLU of North Carolina Legal Foundation, and the Southern Coalition for Social Justice filed a lawsuit challenging North Carolina’s voter suppression law the very day it was signed by Gov. Pat McCrory in August 2013. The suit targets provisions of the law that eliminate a week of early voting, end same-day registration, and prohibit “out-of-precinct” voting. It seeks to stop North Carolina from applying these provisions, arguing that they unduly burden the right to vote and discriminate against African-American voters, in violation of the U.S. Constitution’s equal protection clause and Section 2 of the Voting Rights Act of 1965.
