Axios Des Moines: Local advocates made their case to Polk County supervisors last week on why community IDs would help remove barriers in the area, especially for undocumented immigrants. Now, it's up to supervisors to decide if they want to pursue the program. Iowa Migrant Movement for Justice, an immigrant advocacy group, has asked Polk County to consider offering government-issued photo IDs. A government-issued ID can help individuals verify their identity, build credit and gain access to health care services, among other things, advocates say.
