PHOENIX (AP) -- Nearly 300 people have gathered in Phoenix to protest deportations as well as the inability of some immigrants to get driver's licenses.Demonstrators marched more than a mile Saturday afternoon to the office of the U.S. Immigration and Customs Enforcement.Carrying white balloons, protesters shouted chants such as "undocumented unafraid."Demonstrators called for Gov. Jan Brewer to allow driver's licenses for young immigrants, or "dreamers," protected under President Obama's Deferred Action for Childhood Arrivals program."Dreamers" is a reference to the DREAM Act, a proposed law that would give legal status to people illegally brought to the U.S. as children.They also called for Obama to halt all deportations while Congress remains deadlocked on immigration reform.The protesters represented 50 state affiliates of the United We Dream, an immigrant youth-led network that is having its national conference in Phoenix.© 2014 The Associated Press.
