The Democratic National Committee (DNC) has also declined to participate in the debate.
ColorOfChange.org, one of the minority activist groups leading the charge against the Fox-sponsored debates, applauded Obama, Edwards and the DNC for their decisions.
The group also called on Sen. Hillary Rodham Clinton (D-N.Y.) and other Democratic presidential candidates to do the same.
When the DNC announced last week it would sponsor six debates, the committee almost immediately added that a Fox-sponsored debate would not be among them, citing the news network’s conservative leaning.
However, the committee, Obama and Edwards say they are embracing a debate sponsored by CNN and the Congressional Black Caucus.
