From the Palmetto Scoop:

A source inside the beltway informed me that high ranking officials throughout Virginia were recently summoned to the governor's office for an emergency meeting which reportedly involved discussions on the line of succession if and when Kaine steps down to become Obama's running mate.

The officials were mandated to leave an out-of-state conference and return to the state capitol in Richmond immediately.

Due to the confidential nature of the meeting, details are scarce but the source said that either Obama will choose Kaine, or Kaine was given the impression that he would be chosen.

We're not surprised this kind of rumor is coming out even if it's not true. With everyone trying to get an edge on the choice the rumors will be flying.
