Five NASCAR Drivers Decline President Obama's White House Invitation

(By Jeff Gluck, SBNation.com) - President Barack Obama will honor NASCAR champion Jimmie Johnson and the 11 other Chase drivers from last year in a White House ceremony on Wednesday – but nearly half of the 2010 playoff contenders won't be there.

NASCAR said Thursday that five drivers – Greg Biffle, Kurt Busch, Carl Edwards, Kevin Harvick and Tony Stewart – will not be attending the White House visit due to "schedule conflicts."
