Vice President Joe Biden wants the advice of Jody Baumgartner, an East Carolina University political science professor.

Baumgartner is one of six experts on the vice presidency who have been invited to have dinner with Biden next Tuesday at the vice president's house, Rob Christensen reports.

Baumgartner and the other professors are expected to discuss how past vice presidents have used the post.

He is the author of numerous articles and a book on the vice presidency including "The American Vice Presidency Reconsidered" and "Scoundrel or Uber Lieutenant? The Vice Presidency of Dick Cheney."
