"My friends, I will fight for the endorsement of John Edwards, even if it takes all summer," she told supporters in Louisville, Kentucky. "I have not begun to fight for this endorsement!"
The New York senator appeared to brush off Mr. Edwards' endorsement of Sen. Obama, saying, "I don't know what that has to do with anything."
While Sen. Clinton acknowledged that Sen. Edwards had made a joint appearance with Sen. Obama in which he endorsed the Illinois senator, she said, "If you think that's going to make me give up trying to get John Edwards' endorsement, you've got another thing coming."
She said that she was also "unconcerned" that Sen. Edwards had recently gotten a new phone number and not shared it with her. "Anyone who believes that I'm going to be deterred by an obstacle like that doesn't know what I'm made of," she said. "Mark my words, I am going to get that endorsement."
Sen. Clinton's aides refused to comment on her quest for Edwards' endorsement, saying that they were too busy hiding copies of this week's Time magazine from her.
