Who called from 8477737530

I don't know anybody from Itasca IL but I believe it's another scammer. This was on 12/13/13 @ 2:31 PM CT on a Landline. BLEEP!

Received a call on 12/13/2013 at 02:38 PM.  Left no message.  Caller ID shows only a phone number.

Called on 12/16 at 4:10 PM. It's Tammy Duckworth's office. She left an automated message.

Well, THANK YOU to Blanster for saying it's Tammy Duckworth's #. Why don't the recording leave a message? It just cuts off.

This is a message from Representative Tammy Duckworth informing her constituents of an informational meeting regarding the Affordable Care Act.  It is a legitimate call.  I did not answer but the message was left.
