The George Zimmerman verdict is challenging assumptions about race in America. It started a new national discussion, that we are continuing in our town hall tonight. We are taking an up close look at the hidden bias that often goes unspoken in our society, and surfaces in unexpected ways. It's something President Obama addressed in his remarks following the Zimmerman verdict. It's an issue I discussed with Grammy nominated hip-hop artist Nas; BET's Michaela Angela Davis; David Webb, co-founder of Tea Party 365; New York Times Op-Ed Columnist Charles Blow; and Andre Perry, founding Dean of Urban Education at Davenport University.
