Coming Up on This Week with George Stephanopoulos

This Sunday, ABC's Senior National Correspondent Jake Tapper fills in as moderator of the show.

In two exclusive interviews Jake talks with New Mexico Governor Bill Richardson, and then, Louisiana Governor Bobby Jindal -- two VP contenders -- about the 2008 campaign.

On the "Roundtable," New York Times' Matt Bai, ABC Consultant Torie Clarke, and ABC New's Cokie Roberts, and George Will join Jake to debate the week's politics.
