I have been receiving calls from this number. After reading your comments I decided to answer today - on a Saturday morning. It is the ANA PAC (Political Action Committee). The caller did confirm he was calling to request money. Shame on you ANA.
I'm a nurse, and received a call from this number. They probably got my name from a list. Thanks for posting your info (that it was ANA) relieved my mind.
so here's a second to the "It's the ANA calling" answer.
