(AP) — A north San Diego suburb's planning commission on Tuesday ratified its rejection of a proposed 96-bed shelter for unaccompanied immigrant children who are arrested by the Border Patrol, while the American Civil Liberties Union said it was mulling a legal challenge. About 200 people packed into City Hall chambers, and a large, overflow crowd cheered and jeered below an outdoor speaker as Escondido commissioners heard impassioned pleas, mostly from people urging them to reconsider. Alexia Rodriguez, Southwest Key's vice president of immigrant children's services and legal counsel, said the San Antonio-based group was unaware of Escondido's fraught history with illegal immigration when it did a nationwide search for shelter space in response to a surge of illegal crossings by unaccompanied children from Guatemala, El Salvador and Honduras.
