Coming Up on 'This Week': Sen. Jack Reed, Sen. Bob Corker, Sen. Joe Manchin and Jon Huntsman

NEW YORK, Jan.11, 2013 — -- Two powerhouse roundtables join George Stephanopoulos to tackle the latest challenges at home and abroad, Sunday on "This Week."

As President Obama announces his new national security team, Armed Services Committee member Sen. Jack Reed, D-R.I., and Sen. Bob Corker, R-Tenn., ranking member of the Foreign Relations Committee, join Council on Foreign Relations President Richard Haass and ABC News Global Affairs Correspondent Martha Raddatz to discuss the nominations, plus the debate over Afghanistan and the latest threats from Iran.

Will former Sen. Chuck Hagel survive contentious confirmation hearings to become the next defense secretary? As Hamid Karzai visits Washington, how many troops should the U.S. keep in Afghanistan? And will Iran pose the greatest challenge overseas in President Obama's second term? Our foreign policy roundtable tackles those topics and more, Sunday on "This Week."

Then, the powerhouse political roundtable breaks down the domestic battles ahead, from the looming budget cliffs to the gun control debate to the fight over President Obama's Cabinet picks, with Nobel Prize-winning economist and New York Times columnist Paul Krugman; Wall Street Journal columnist Peggy Noonan; Bloomberg News executive editor Al Hunt; "PBS NewsHour" co-anchor and senior correspondent Judy Woodruff; and David Walker, former U.S. comptroller general and founder and CEO of the Comeback America Initiative.

Plus, Sen. Joe Manchin, D-W.Va., and former Utah Gov. Jon Huntsman, honorary chairs of No Labels, tackle whether both parties can ever come together in Washington.
