Coming up… EXCLUSIVE: BP America Chairman and President Lamar McKay, Napolitano and Salazar

Plus a Powerhouse Roundtable: Will, Maher, Sharpton, Dowd and vanden Heuvel

— -- On Sunday, we'll have the latest breaking news from the Gulf of Mexico as BP America Chairman and President Lamar McKay comes to "This Week" for an exclusive interview. With an environmental and economic disaster growing by the hour, "This Week" anchor Jake Tapper will ask Mr. McKay about BP's response to the oil spill and how the company intends to stop the hundreds of thousands of gallons of oil leaking every day into the Gulf.

Secretary of Homeland Security Janet Napolitano and Interior Secretary Ken Salazar join Jake for the latest on the oil spill as the federal government sends more resources and even readies a naval response. Plus, the debate over immigration. Arizona's crackdown on illegal immigrants has raised questions about how much can be done to control our borders and whether the federal government is doing enough? We'll put those questions to Secretary Napolitano, who was governor of Arizona before being appointed to her current Cabinet position.

Then a special, powerhouse roundtable with Bill Maher, host of HBO's Real Time, Rev. Al Sharpton, former Bush political strategist Matthew Dowd, Katrina vanden Heuvel of the Nation, and George Will. A diversity of voices matched only by the diversity of topics. They'll weigh in on the immigration debate, politics and Governor Crist's bolt from the Republican Party, new rules for Wall Street, the Senate hearing with Goldman executives, and, finally, what some call "nerd prom" -- the White House Correspondents Dinner -- for reporters, politicians and stars.

You won't want to miss it. Sunday morning
