"Give me a break. This whole thing is the biggest fairy tale I've ever seen," Clinton said at the time, referring to Obama's claim that he, unlike Hillary, had been consistently opposed to the Iraq War.
In South Carolina, the former president blasted CNN reporter Jessica Yellin, charging that stories about voters being turned off by his recent rhetoric, and stories about racial issues entering the presidential contest, had been purely media driven.
"You wanna make this about words and name calling. I hate it," he said. "They're feeding you this because they know this is what you want. This is what you live for ... One more story. Shame on you. Shame on you!"
He garnered more media attention when he compared Obama's South Carolina victory to Jesse Jackson's wins in the state in the 1980s.
"Jesse Jackson won South Carolina in '84 and '88. Jackson ran a good campaign. And Obama ran a good campaign here," he said.
Asked whether her husband contributed to her defeat in South Carolina, Hillary Clinton told the New York Daily News' editorial board, "It may have," she said.
"It's hard to sort out all the different factors that influence people's perceptions and their votes."
Democrats, like former Sen. Tom Daschle, D-S.D., said the former president's recent comments were "not presidential," and others accused him of tarnishing his reputation as an elder statesman, and of creating divisions within the Democratic Party.
Donna Brazile, a Democratic analyst and ABC NEWS contributor, who headed Vice President Al Gore's campaign in 2000, said Bill Clinton appears to have stopped playing offense.
"He's returning to the role that he played in the first couple months of her election, and that is raising money and keeping the faithful energized," said Brazile.
Brazile likened the outspoken role Clinton was playing to one that a vice presidential candidate often plays in general election campaigns.
"It doesn't appear that he's going to play that role anymore, which I think is good for her, and I also think it's good for the Democratic Party, and good for the process," she said.
Today, Hillary Clinton emphasized that she intends to focus her campaign message on the issues.
"I think that is what voters want to hear," Clinton told ABC NEWS. "This election is about you, it's about the American voter, it's about you sitting at home, watching this, it's about you reading this, it's about your jobs, it's about your health care, your futures, and that's what I want to stay focused on."
