Earlier on Monday, during a breakfast gathering, Hillary Clinton urged her supporters to unite behind Barack Obama. She said Democrats could not afford to let lingering frustrations from their nominating battle hurt Obama’s bid for the White House.

Sen. Hillary Clinton: “The McCain campaign is running ads trying to divide us. And let me state what I think about their tactics and these ads. I’m Hillary Clinton, and I do not approve that message.”

Clinton is giving a prime-time speech tonight at the convention. She is expected to meet with her delegates on Wednesday to free them from their commitment to vote for her and urge them to back Obama.
