National Guard to end sponsorship of Dale Earnhardt Jr. and Graham Rahal

The National Guard said Wednesday it will end its sponsorship of NASCAR driver Dale Earnhardt Jr. and IndyCar driver Graham Rahal, but it is not clear when that goes into effect.

Hendrick Motorsports said in a statement it has a contract with the Guard through 2015 and there have not been discussions to change that deal.

A spokesperson for Rahal Letterman Lanigan Racing did not immediately return a request for comment on the status of the Guard's sponsorship in IndyCar.

The Guard said in a statement posted on its web site it spent $32 million on its NASCAR sponsorship and $12 million on its IndyCar sponsorship this year. Sen. Claire McCaskill has led a push in Congress to end military sponsorships, calling the funding "wasting a bunch of money."
