Democratic presidential hopeful Senator Hillary Clinton (from New York) on Thursday announced that she will end her historic bid to become president on Saturday. In a e-mail letter addressed to supporters, Clinton said that she is ready to support Democratic rival Senator Barack Obama (from Illinois) in his bid for the White House. Clinton's promise of support came a day after Obama received the necessary number of delegates to secure the party's nomination. “On Saturday, I will extend my congratulations to Senator Obama and my support for his candidacy. This has been a long and hard-fought campaign, but as I have always said, my differences with Senator Obama are small compared to the differences we have with Senator McCain and the Republicans. I have said throughout the campaign that I would strongly support Senator Obama if he were the Democratic Party's nominee, and I intend to deliver on that promise,” Clinton said in her letter. Clinton is set to hold a rally on Saturday in Washington, DC to thank her supporters and work to unite the Democratic party behind Obama. There is no indication whether Clinton has been asked to run with Obama as Vice President, though she has privately said that she is open to the idea. When asked about inviting Clinton onto the ticket, Obama on Thursday said “we're not going to be rushed into it. I don't think Senator Clinton expects a quick decision and I don't even know that she's necessarily interested in that [taking the Vice President spot in the campaign].”
