Coming up: Speaker Nancy Pelosi, Sen. Lamar Alexander

— -- Can House Speaker Nancy Pelosi revive health care reform? Sunday, on "This Week", Speaker Pelosi sits down with 20/20 anchor Elizabeth Vargas in her first network interview after the health care summit. Did the summit save health care reform? Will the Democrats resort to a plan B? What are the party's prospects for 2010?

Then, the Republican point man at the health care reform summit, Senator Lamar Alexander takes on the President and congressional Democrats on health care reform. And was the Senate vote on the jobs bill a sign that perhaps there might be hope for bipartisanship?

Plus our Roundtable: George Will, Cokie Roberts, Sam Donaldson and Paul Krugman take on the health care debate, will Democrats push a bill through using reconciliation? With stubbornly high unemployment hobbling the economy, is the jobs package too little, too late? Toyota takes a beating in Congress, but hearings leave a lot of unanswered question about how to best keep cars safe. And he's back. George W Bush meets for the first time with Dick Cheney since he left office.

See you Sunday. You won't want to miss it.
