Senator Hillary Clinton plans to officially end her campaign.

Late on June 4, the Clintons said goodbye to their guests after a small birthday party for Hillary's mother.

It was a brief distraction from a tough day.

Sunglasses firmly in place, Hillary Clinton marched into her headquarters and faced a staff that had just been told they were losing their jobs.

She managed a smile afterward, but the meeting brought some staffers to tears.

Many of Clinton's supporters in Congress had been urging her to let them break for Obama.

"I really think we ought to get on with endorsements and dealing with what we have to deal with, even if that includes the Vice Presidency, so that we can move forward," stated Rep. Charles Rangel, (D, NY).

And will her future include the Vice Presidency?

"Normally politicians don't want to be outshone," said Pennsylvania Governor, Ed Rendell.

"Hillary Clinton, a very charismatic figure for many Americans, generally a lot of politicians don't like to put somebody like that on the ticket."

In an interview with a London newspaper, former President Jimmy Carter shot down the idea too.

"I think it would be the worst mistake that could be made," exclaimed Carter.

Obama has tapped Caroline Kennedy to help him decide.

He told Charlie Gibson he looks forward to meeting with Clinton, but his decision won't be rushed.

"I think it's very important for me to meet with her and talk to her about how we move this party forward," stated Obama.

"But I also believe that it's very important for me to, when it comes to choosing a Vice President, to do it in a deliberative way."

Clinton has told supporters she's open to the possibility of the Vice Presidency, but she's just as happy to return to the Senate.

Still, that won't be easy because many of her Senate friends endorsed Obama.
