WASHINGTON - Hillary Rodham Clinton will concede Tuesday night that Barack Obama has the delegates to secure the Democratic nomination, campaign officials said, effectively ending her bid to be the nation's first female president...

EDIT: Now her campaign is denying it.

SECOND EDIT:
On NBC's "Today Show," Clinton campaign chairman Terry McAuliffe said that once Obama gets the majority of convention delegates, "I think Hillary Clinton will congratulate him and call him the nominee."

In a formal statement, the campaign made clear the limits of how far she would go in Tuesday night's speech. "Senator Clinton will not concede the nomination," the statement said.
