Obama Veep Pick To Come Friday

CBS News has confirmed that Barack Obama's campaign now plans to announce Obama's vice presidential choice to supporters via email and text message on Friday afternoon. (This plan could change, of course.)

He will then appear with his running mate at noon the next day in Springfield, Illinois, CBS News chief political consultant Marc Ambinder reports.

Media reports today have suggested that Indiana Senator Evan Bayh, Virginia Gov. Tim Kaine and Delaware Senator Joseph Biden as the names now atop Obama's list.
