It's South Texas Project, led by Harrington, became the Texas Civil Rights Project in September 1990. The establishment of Texas Civil Rights Project marked the end of Harrington working for the Texas Civil Liberties Union. He said that the TCLU more interested in classic civil liberties issues, like free speech, while he was focused on racial justice issues. Under Harrington's leadership, the TCRP had a significant impact, winning many civil rights cases. These included the areas of disability rights, rural economic justice, compliance with Title IX, the criminal justice system, racial discrimination, police brutality and the right to privacy. After leading the TCRP for 25 years Harrington retired in 2015. In a departing piece published in the Texas Observer, he expressed his passion for civil rights and his desire to continue to serve, but by working "directly with people in a different way."
