(CNN) - After days of growing debate about his prominent role in her campaign efforts, Sen. Hillary Clinton said Sunday she knows how her husband feels.
"You know, I think that what he is doing for me is obviously out of a sense of deep commitment to me personally, but also based on his experience as president as to who he thinks would best lead our country," Clinton told CBS' "Face the Nation."
"And I know that in my own support of him going back some years, I sometimes got a little bit carried away. I confess to that."
Asked by host Bob Schieffer whether the former president has gotten "carried away," Hillary Clinton laughed and responded, "I think it's human nature, Bob. I think that the spouses of all three of us have, you know, been passionate and vigorous defenders of each of us and, you know, maybe got a little carried away. But, you know, that comes with a hard-fought election.
"It also comes with sleep deprivation which, you know, I think is marking all of us, our families, our supporters."
Critics have complained about some of Bill Clinton's remarks on the trail for his wife in South Carolina, including his reference to Jesse Jackson having won primaries in the state in the 1980s.
The remark was widely seen as a suggestion that Obama's success would be largely based on his race. In the end, Obama won with a large majority of African-American voters, while most whites voted for Clinton or Sen. John Edwards.
Obama, speaking Sunday on ABC's "This Week," sidestepped a question about whether the former president's remark was a matter of "racial politics."
"I think that that's his frame of reference, was the Jesse Jackson races," Obama said.
Hillary Clinton told CBS, "I am very, very proud of my husband's record as a leader in our country going back so many years and what he's done. And people know his heart. They know, you know, what he has stood for.
"So, I'm really glad that he's there with me, and I think everybody just needs to take a deep breath. We need to be focusing on what's important in the lives of Americans."
