This phone number calls me at least once a day on weekdays. It appears to be a local number with the ID "Amarillo TX" which is near where I live. I accidentally answered today since I had recently had a call from a local business with the ID "Amarillo TX" but a different phone number and I was expecting a call back from that business. I just didn't look carefully at the number. The person on the phone said they were with Citizens United from Washington DC. When I asked about the fact that their number appeared local, she said they use a WATS line and the phone company determines what the caller ID shows. I'm not sure if I spelled that right but when googling WATS it doesn't sound like that it something that is still in use.
