Rep. Chris Van Hollen has agreed to play the part of GOP vice presidential candidate Paul Ryan in debate prep, according to an Obama campaign official.
Van Hollen's stand-in role is fitting — the Maryland Democrat serves as the ranking member on the House Budget Committee. Rep. Ryan (R-Wis.) is the chairman of that panel.
Sen. John Kerry (D-Mass.) will be playing the part of Romney in President Obama's debate practice.
