FILE - In this April 13, 2011, file photo House Budget Committee Chairman Paul Ryan, R-Wis., takes questions in reaction to President Obama's speech on a federal spending plan, during a news conference at the Capitol in Washington. Ryan initially established his reputation in Congress mostly behind-the-scene, impressing GOP colleagues with his willingness to delve into complex number-crunching and budgetary minutia. But he has become in the past couple of years one of the highest-profile and influential members of the House, to the point that he engaged in verbal showdowns with President Barack Obama.
