Republican presidential candidate Mitt Romney has selected Wisconsin Rep. Paul Ryan to be his running mate.
The candidate made his announcement to supporters via a phone app, saying -- quote -- "Mitt's Choice for VP is Paul Ryan." The GOP ticket was set to appear together at 9 A.M. Eastern in Norfolk, Va.
Romney and Ryan are kicking off a four-day bus tour that will take them to as many states.
Ryan, just 42 years old, is a darling among fiscal conservatives. As chairman of the House Budget Committee he's been front and center in the battles over spending cuts and entitlement reform.
For all the reasons republicans like Paul Ryan democrats see ample opportunity to attack. In March, House Republicans passed Ryan's "Path to Prosperity" budget plan which would have slashed trillions of dollars in Federal spending over the next decade.
