Obama Campaigns With Potential Running Mates Bayh, Nunn

(CBS)
(CHICAGO) Barack Obama hits the campaign trail today with possible vice presidential contenders, Sen. Evan Bayh, D-Ind., and former Sen. Sam Nunn, D-Ga. Obama has vowed not to discuss potential VP choices or the vetting process with the press, but recently he has been seen whizzing in and out of the office of his VP vetter, Eric Holder. He was also recently accompanied to New York by Caroline Kennedy, another member of his VP search committee.
Obama, Bayh, and Nunn will speak at a campaign event at Purdue University in Indiana this afternoon, where they will discuss modern day national security threats, which include bioterrorism and cyber security.
Also on the trail today is Davis Guggenheim, the Academy Award winning director of Al Gore's documentary, “An Inconvenient Truth.” Guggenheim, accompanied by his camera crew, will be traveling to Indiana on Obama’s press plane. Guggenheim is working on an Obama documentary for the convention.
