Guests on ABC News “This Week” for Sunday, June 6, 2010

On Sunday, National Incident Commander Admiral Thad Allen gives the latest on the growing environmental catastrophe along the Gulf of Mexico, whether the clean-up operation is too little, too late, and if the government’s worst case scenario is becoming a reality.

Then, Senate Foreign Relations Committee Chairman John Kerry (D-MA) and National Republican Senatorial Committee Chairman John Cornyn (R-TX) EXCLUSIVELY speak with “This Week” anchor Jake Tapper about how the U.S. should move forward after Israel’s controversial raid on a flotilla attempting to break the blockade of Gaza. The two also weigh in on the BP oil spill, the momentum it could possibly provide for Senator Kerry’s energy and climate bill, and whether Senator Cornyn will still support a “drill baby drill” approach as the spill threatens his home state of Texas.

And on the round table: ABC News’ George Will, Markos Moulitsas, founder of the Daily Kos, Arianna Huffington of the Huffington Post and former Deputy Assistant Secretary of State Liz Cheney of Keep America Safe discuss the political problems stemming from the oil spill, how Israel’s deadly flotilla raid will affect the Middle East peace process, and whether an almost perfect game should change American’s favorite pastime.

Ian Cameron is the executive producer of This Week. The program airs Sundays on the ABC Television Network (check local listings).
