Virginia‘s Republican candidate for Senate, Ed Gillespie, has released a new ad hitting Sen. Mark Warner, D-Va., for his use of private planes.

A recent USA Today article released last week thrust charter planes into some campaigns, including Virginia’s Senate race. It was revealed that Warner used a charter plane for a recent trip to Southwest Virginia that cost taxpayers $8,500. By comparison, Sen. Tim Kaine, D-Va. took a similar trip to that part of the state, but drove by car. His travel expenses were less than $700.
