Coming Up on This Week with George Stephanopoulos

This Sunday, George is joined by Sen. Joe Biden, D-Del., to discuss President Bush's remarks to the Israeli Knesset earlier this week. Was Bush engaging in partisan politics overseas? Biden discusses the president's role in campaign '08 and the troubles for the GOP at home.

Then, George talks with House Republican Leader Rep. John Boehner about the Republicans' striking loss in Mississippi and what it could mean for the party in November.

And, on the "Roundtable," Wall Street Journal columnist and author Peggy Noonan, the New York Times' Matt Bai, and ABC News' Donna Brazile and George Will debate the week's politics.

Tune in Sunday when "This Week" is back at the Newseum.
