This Sunday, "This Week" covers the latest in the battle against ISIS and the debate over President Obama's proposed authorization of force, with Iraq War veteran Rep. Adam Kinzinger, R-Illinois, and House Intelligence Committee ranking member Rep. Adam Schiff, D-California.

And the powerhouse roundtable debates all the week's politics, with ABC News contributor and Democratic strategist Donna Brazile, ABC News contributor and Republican strategist Ana Navarro, Washington Post national political reporter Robert Costa, and Politico editor and co-founder Jim VandeHei.
