A Mexican immigrant rights activist deported earlier this month may be headed back to the United States as a Mexican government envoy. Elvira Arellano has asked Mexican President Felipe Calderon to appoint her “peace and justice ambassador” so she may return to be with her U.S.-born, eight-year-old son. Arellano was deported earlier this month following a year of refuge inside a Chicago church. She was arrested outside a Los Angeles church after arriving to take part in a rally for immigrant rights.
