State roll call makes it official, GOP nominates Mitt Romney for president at convention

Mitt Romney claimed the GOP nomination for president Tuesday afternoon on the first full day of a storm-shortened national convention in Tampa, Fla. Romney won his party's formal appointment well into the traditional roll call of states, securing enough delegates to win.

Romney's vice presidential pick, Rep. Paul Ryan, is expected to be nominated shortly. Romney, 65, served as governor of Massachusetts for one term but has steered much of his campaign on his business background as a consultant and venture capitalist. He is the first Mormon to serve as a major party presidential nominee.
