In a statement released by Obama's campaign Sunday afternoon, former South Carolina State Rep. "I.S." Leevy Johnson, an Obama supporter, said he was offended Clinton did not condemn Johnson's comments.
“It’s offensive that Senator Clinton literally stood by and said nothing as another one of her campaign’s top supporters launched a personal, divisive attack on Barack Obama,” he said. “For someone who decries the politics of personal destruction, she should’ve immediately denounced these attacks on the spot.”
Clinton's campaign says Johnson was not referring to Obama's past drug use, but rather his career as an organizer and state legislator. Meanwhile, Rep. Stephanie Tubbs Jones, another African-American supporter of Clinton, said of the comments, "Sometimes people say things that aren't sanctioned … I can't speak for Bob."
