Ruben Moreno, part of Mariachi Luz de Luna, played "The Star-Spangled Banner" during a brief exchange between protestors and immigrant rights activists in Oracle, Ariz.

Dozens of protestors were gathered north of Tucson today waiting for the expected arrival of a busload of immigrant children who were to be housed at a holding facility for young people in the town of Oracle. By the afternoon it was confirmed the bus would not be arriving to the site today.
