COLUMBIA, S.C. - A group formed to garner support for President Bush's judicial nominees has launched a second attack ad in South Carolina against Democratic presidential hopeful John Edwards.

The Committee for Justice first ran three days of 30-second ads earlier this month. The group on Monday announced its second run of ads, which features another Democratic presidential candidate, the Rev. Al Sharpton.

Earlier this month, Sean Rushton, executive director of the Committee for Justice, said Edwards was singled out in the ad campaign because the North Carolina senator has staked much of his presidential bid on his showing in South Carolina's early 2004 primary.

The ad depicts California Supreme Court Justice Janice Rogers Brown growing up as the daughter of a sharecropper and becoming the only black member of the California high court. Bush has nominated the conservative jurist to the U.S. Court of Appeals for the District of Columbia.

The ad says Brown's nomination is being blocked by Edwards. It also shows Sharpton saying, "She should get an up-or-down vote."

"I don't think she should be opposed because she doesn't come from some assumed club," Sharpton says in the commercial.

But in a release Tuesday, Sharpton said the ad uses his name and statements in a misleading manner. He asked that the ad be pulled from the air and that the group issue an apology.

A message left Tuesday evening with the Committee for Justice was not immediately returned.

Sharpton said he is opposed to Brown's nomination and supports Edwards' stance.

"Sen. Edwards properly voted against Janice Rogers Brown after a careful and deliberative review of her right wing judicial findings - not her politics - and at the urging of myself and other civil rights leaders," Sharpton said.

Edwards, meanwhile, said he stands firm in his opposition of Brown.

"Political attacks from White House front groups won't change what I believe nor will they change my actions," he said.
