President Barack Obama plans to tap into a national religious network to advance his health care agenda with a telephone appearance on Aug. 19.A coalition of interfaith religious groups backing health care reform has launched a 40-day campaign targeting 100 Members of Congress with a variety of local faith-based events and landed Obama as the headliner for a telephone call-in event next week.The campaign also features a low-budget TV ad showing Christians advocating for reform and asking Members to do so as well.

You are going to hear the moral drumbeat throughout this debate.—The campaign is sponsored and organized by PICO National Network, Faith in Public Life, Faithful America, Sojourners and Catholics in Alliance for the Common Good.
