HENDERSON, Nev. (AP) — President Barack Obama is shrugging off Republican criticism of his actions to lift the threat of deportation from millions of immigrants living illegally in the United States. In an interview broadcast Sunday on ABC's "This Week," Obama said it was important that he act unilaterally to prioritize the deportation of criminals and recent arrivals and spare those who have lived here illegally for at least five years and have roots, including children who are American citizens.
