Why don't we hear about Saudi Arabia providing weapons, fighters and money to the Sunni Insurgents in Iraq?

Our leaders keep telling me about all the things Iran is doing to arm the fighters attacking our troops in Iraq, but I don't hear the administration or Sen McCain (the Heir Apparent) talking about the Saudi's providing support for the Sunni Fighters attacking our troops in Iraq and the ACM/AAF fighting our troops in Afganistan? Why is this?
