(CNN) - John Edwards said Friday that Barack Obama needs to “speak up, if he really means what he says” about ending divisive politics and denounce a Nevada ad funded by an independent group that supports the Illinois senator’s presidential bid.
The spot, running on Spanish-language radio in the state, criticizes Hillary Clinton for a lawsuit filed by some of her Nevada supporters that had sought new restrictions workplace caucus sites this Saturday. The buy is funded by the Unite Here Campaign Committee on behalf of the Culinary Workers Union, which has endorsed Obama.
"Everyone pledged that this kind of divisive politics that divides the Democratic Party, and could divide America, would come to an end. Sen. Obama made that pledge, I was sitting five feet from him when he made it," Edwards told the crowd at a Nevada campaign event.
“And now it turns out that in the last 24 hours there's a radio ad, a malicious radio ad, attacking Sen. Clinton. That is exactly the kind of divisive politics. It's being run right here, in Las Vegas. I denounce it. This kind of ad, I don't care who's doing it - in this case it's Sen. Obama's supporters - but this sort of thing needs to stop.
“And from what I've seen, Sen. Obama has not said a single word about this. Nothing. When two days ago, three days ago, he said on a stage in front of America and said, 'This kind of politics has no place in America,’” said Edwards.
“He should speak up, if he really means what he says, and this is not just talk, he should speak up and denounce this type of divisive politics.”
John Edwards was criticized by Obama in Iowa for not calling an independent group that supported the former North Carolina senator to demand they pull ads they were running in support of his candidacy.
The Obama campaign has not yet responded to Friday’s remarks from Edwards.
On Thursday, the Clinton and Edwards campaigns both took aim at Obama over the ad, which refers to the recent lawsuit over casino caucus sites by supporters of the New York senator’s presidential bid, saying it shows that “Hillary Clinton does not respect our people. …Hillary Clinton is shameless. Hillary Clinton should not allow her friends to attack our people’s right to vote this Saturday.”
The spot also praises Obama, saying that “Sen. Obama is defending our right to vote. … He respects our votes, our community, and our people.”
The Clinton campaign has expressed frustration with the fact that the spots are continuing to run, even though a judge ruled against the suit.
