A spokesman for likely Democratic presidential nominee Barack Obama says he and Hillary Rodham Clinton met face to face on Thursday to talk about uniting the Democratic Party. The spokesman, Robert Gibbs, said that the two former rivals wanted to talk about "bringing their campaigns together in unity." Gibbs would not say where they met, except that it was not at Clinton's house in Washington, as was widely reported in the media. Obama earned enough delegates Tuesday night to clinch the Democratic presidential nomination. Clinton plans to announce on Saturday that she is supporting the Illinois senator.
