Once fierce rivals for their party's nomination, Obama and Clinton will make their most public display of unity to date next Friday.
The two Democrats will campaign together then, the Obama campaign announced. No word yet as to where they will do it or how.
The e-mail release simply stated, "Further details to be announced soon."
*** UPDATE *** In a conference call today, the Obama camp said, it is "still hammering out some of the logistical details, and when we have those we'll let you know."
