Coming Up on 'This Week': Powerhouse Roundtable

WASHINGTON, May 24, 2012— -- Check back Friday morning to find out our exclusive "This Week" headliner guest.

Coming up this Sunday, "This Week" debates all of the week's politics with our powerhouse roundtable: ABC News' George Will, former Michigan Gov. Jennifer Granholm, Fox Business Network anchor Liz Claman, the Washington Post's Nia-Malika Henderson, and Ron Brownstein of National Journal.

President Obama and his team have doubled down on the Bain Capital attacks against former Massachusetts Gov. Mitt Romney, but is the argument resonating with voters? And can the president withstand criticism from members of his own party over the attacks?

And, there is more fallout from the botched Facebook IPO. As regulators open investigations and investors file suit, what's next for the social media pioneer?
