The ACLU of Texas on April 8, 2020 filed a complaint against the U.S. Immigration and Customs Enforcement (ICE) and Department of Homeland Security (DHS) after an employee located at an ICE Montgomery Processing Center (MPC) in Conroe, Texas tested positive for COVID-19. The complaint asks that illegal immigrants that are more susceptible to COVID-19 be released. This is part of a national attempt by the ACLU to release illegal immigrants as over twenty similar cases have been filed by the ACLU across the country.

Objections to PACR and HARP
The ACLU of Texas along with other ACLU affiliates has filed a petition objecting to the Department of Homeland Security’s Prompt Asylum Claim Review (PACR) and the Humanitarian Asylum Review Process (HARP). The ACLU of Texas argues that expedited processes by which Customs and Border Protection (CBP) processes applications violate the law by preventing proper opportunity to provide a defense against a claim an immigrant is unlawfully present or stating reasons why an applicant qualifies as an asylum seeker. 
The ACLU Foundation of Texas provides information regarding the scope of abortion rights in Texas including: informing children under 18 that they can receive an abortion (as well as how to get an abortion without parental consent through legal emancipation), instructs women that despite doctors being mandated to display images of a sonogram prior to abortion and to report the results of a sonogram such as identifying a heartbeat that they are entitled to not listen or divert their attention from the communication, and instructs readers who cannot afford an abortion to seek-out clinics or visit the webpage for the National Network of Abortion Funds. 
Gender and Sexuality Alliance
The ACLU Foundation of Texas provides information on how students can form Gender and Sexuality Alliance organizations as school or university clubs that receive funding from the school or university. 
The information provided includes instructions on student rights under the federal Equal Access Act to form any non-curricular club they want (so long as the school does not have a general ban on non-curricular clubs) and that they should insist on their right to form a club if confronted with hesitance from the university.
