A Weakened Bush Meets with Other World Leaders at the G8

Hosted by

At the G8 Summit which opens tomorrow, George Bush faces a tough sell for his global warming proposal, particularly from Germany's new conservative leader, a natural ally who has a plan of her own.  At home, the President's approval ratings are low, and even his conservative supporters are angry at him over his immigration bill. What's a lame-duck president to do?  Also, Scooter Libby gets 30 years for his role in the Valerie Plame case and, on Reporter's Notebook, the war that re-shaped the Middle East started forty years ago today.  Sara Terry guest hosts.
