Asked about criticism from Republicans that he hasn't fully explained his personal story to voters, Romney laughed off the suggestion, telling Williams that he's been more than open about his life.
"I'm happy to talk about my heritage… I'm proud of my heritage," Romney said, noting that his father was born in Mexico and mentioning his membership in the Mormon church. But he argued it was still too early for most voters, suggesting most people won't start paying attention to the presidential race until after Labor Day.
"Most folks won't really get to see me until the debates and will get a better sense of the character that I have," Romney said.
He declined to offer any details about his search for a vice presidential running mate. Williams asked Romney the suggestion among Republicans that he would pick "an incredibly boring white guy."
"You told me you were not available," Romney joked.
