Mitt Romney’s decisive win in the Florida Republican primaries set the stage in political coverage this week – with Romney’s latest gaffe setting off a firestorm, erroneous rumors of a Newt Gingrich endorsement from the Donald, and pundits questioning Gingrich’s staying power.  Politics also entered the non-profit world after the Susan G. Komen Foundation reversed a decision to partially cut off funding for Planned Parenthood.

We also saw headlines from the tech sector, with Facebook’s stock offering expected to value the company at $75 billion to $100 billion and President Obama having some fun with voters’ questions on Google +.

POLITICO’s Jonathan Martin, Roll Call’s Christina Bellatoni and The New York Times’ Michael Shear will be on the show to talk about political coverage.

The Daily Beast’s Michelle Cottle and The Daily Caller’s political reporter Matt Lewis will discuss the fallout over the Susan G. Komen Foundation and Gingrich’s latest media coverage.

Finance writer for Reuters Felix Salmon and University of Maryland professor of media entrepreneurship Mark Potts will discuss Facebook’s new role in the world in the journalism.

This Sunday at 11a.m. EST on CNN.
