In November 2012, Valdez won a third term, defeating Republican challenger Kirk Launius. In 2015, Valdez "changed policies on holding immigrants in the Dallas County jail for federal officials once the person is past his or her release date. People who committed minor offenses aren’t held for up to an additional 48 hours for agents of U.S. Immigration and Customs Enforcement, or ICE." This brought a warning from Governor Greg Abbott to "back down from a policy change on federal immigration detention requests."
