Clinton has constitutent vouch for her

Hillary Clinton calls on a New York constituent in a new television ad that seeks to defend her against criticisms that she is not trustworthy.

Her principal rivals for the Democratic nomination, John Edwards and Barack Obama, have in ads and speeches and during recent debates said she has been disingenuous on various issues. Her critics have been more harsh, accusing her of the same slickness as her husband, the former president.

In the 30-second spot airing in Iowa and New Hampshire, Joseph Ward says that his son needed a bone marrow transplant that his insurance wouldn't pay for and he couldn't afford. He says that Clinton's Senate office interceded and quickly got the hospital to pay for the treatment.

"Now, her opponents are saying that Hillary can't be trusted," Ward says. "I trusted this woman to save my son's life. And she did."
