HOUSTON - The day after hearing from Mitt Romney that he would serve African-Americans better than Barack Obama can, the NAACP has heard a rebuttal of sorts today from Vice President Joe Biden.

He told the group's annual convention in Houston that Romney's agenda would hurt -- and not help -- working families in the black community.

Biden drew cheers as he credited Obama for championing a landmark health care law and launching the mission that killed al-Qaida leader Osama bin Laden.

Earlier, Obama appeared in a taped video message -- telling the NAACP that he stands "on your shoulders."
