Watch Mitt Romney Announce Paul Ryan as Running Mate

Mitt Romney on Saturday morning formally announced he has chosen Rep. Paul Ryan, R-Wisc., as his vice presidential running mate. Calling themselves "America's Comeback Team," the duo promised voters in the battleground state of Virginia they would put the nation back on track if they win on Nov. 6.

Romney had the Norfolk crowd in stitches by accidentally announcing Ryan as the next "president" of the United States. He corrected himself a few minutes later.
