Activist's son in Mexico

Eight-year-old Saul Arellano joined his mother in Mexico on Thursday following her loss in a yearlong fight to stay in the United States despite her status as an undocumented migrant.

Elvira Arellano told a news conference in Tijuana that her son, who was born in the U.S. and is an American citizen, will enter third grade in her native state of Michoacan.

But Arellano said she will continue to travel and work for immigration reform in Mexico City and the border city of Tijuana on behalf of her Latin Family United organization.

Arellano took sanctuary at the Adalberto United Methodist Church in Chicago for about a year in defiance of a deportation order. She left in August and was arrested and deported after giving an immigration speech in Los Angeles.
