Here is a closer look at Mitt Romney's vice presidential pick Wisconsin congressman Paul Ryan.
Paul Ryan was born in Janesville, Wis., in 1970. He is the youngest child of Paul and Elizabeth Ryan.
Ryan was raised Catholic and graduated from Joseph A. Craig High School in Janesville in 1988.
Ryan earned a degree in political science and economics from Miami University in Ohio in 1992. He worked at a family construction company before getting into politics.
Ryan married Janna Little, a tax attorney in December 2000. They currently live in Janesville with their children, daughter Liza and sons Charlie and Sam.
Ryan was first elected to Congress at age 28, and later helped launch the party's "Young Guns" program to recruit candidates in districts where Republicans lost.
Now 42, Ryan is the architect of the House GOP's budget proposal, which Democrats compared to an attack on the poor, but Republicans say is intended to save Medicare and rein in spending.
On Saturday, the Romney campaign announced that Ryan would join the GOP ticket as his running mate.
