Just received a call from this number. Caller ID showed; MISSOURI. When I answered it was a recorded woman's voice, wanting me to "press one to let my Congressman know I'm against international banking". The recorded voice let me know this was sponsored by 'Americans for Prosperity' the non-profit political advocacy group established by the mega-rich Koch brothers.

Supposedly Chesterfield MO.....blocker hung up for me.  There should be a prize when we get an alleged call from each of the 50 states............I think I'm getting close!
