NORFOLK, Va. -- Mitt Romney introduced his choice for running mate, Wisconsin Rep. Paul Ryan, during a speech in Norfolk, Va. Saturday morning. The presumptive Republican nominee for president announced his VP through his app earlier Saturday morning. This comes one day before Romney will travel to North Carolina as part of his four-state bus tour.

"Paul and I are beginning our journey that will bring us to every corner of America," said Romney. "We offer solutions that are bold, specific and achievable."

The pair are being coined as "America's Comeback Team."

"We won't duck the tough issues. We will lead," said Ryan. "We won't blame others. We will take responsibility. We won't replace our founding principles. We will apply them."
