Arizona Republic:  “Confusion surrounding a provision in state law that took effect last month has local governments wondering whether they’ll now have to verify the citizenship of people seeking any public benefit, from a public pool to a library.  The source of the problem: A section in House Bill 2008, signed into law in September as part of the 2010 state budget, that requires those who seek ‘any state or local public benefit’ to prove citizenship by providing a driver’s license, passport or other legal identification.  The law also applies to federal benefits that have citizenship as a requirement for eligibility.”
