The National Association of Black Journalists and its chairman, Cloves Campbell,  are calling on the Commission on Presidential Debates to end its mistreatment  of black reporters as if they were unqualified, invisible, or both.

No blacks will participate in this year's debates.

Candy Crowley of CNN, Jim Lehrer of PBS and Bob Schieffer of CBS News were selected to moderate the three debates between President Barack Obama and Republican challenger Mitt Romney this fall.

Martha Raddatz of ABC News will moderate the debate between Vice President Joe Biden and Republican candidate Paul Ryan.

A commission representative did not immediately return a call seeking comment.
