President Obama, who has been pushing health care all week, takes his case for health care reform to senior citizens. In a ?tele-town hall,? the president will take questions about health care from AARP members via phone, email, and a small live audience. To gather the questions, the group will contact hundreds of thousands of its members with automated “robo-calls” ten minutes before the event. The Takeaway talks to Drew Nannis, spokesman for the AARP, about the town hall.
