Elizabeth Edwards is suggesting that Hillary Clinton is a copycat when it comes to health care policy.

Edwards says the Democratic presidential candidate copied her husband's health care plan that was outlined more than seven months ago.

Edwards also says the New York senator has failed to lead on an issue in which she has extensive experience.

Her comments came yesterday at an appearance in Columbia, South Carolina.

Elizabeth Edwards has been one of Clinton's sharpest critics.

Clinton's campaign has responded by saying the senator has worked harder and longer than anyone to improve health care in the U.S.
