“She has an open invitation to come talk to me,” Couric said during a stop Monday in Orlando. “I’m not sure she’d be interested, but she’d certainly be welcome. She’s a fascinating figure not only on the political scene but in popular culture.”

“I have no regrets about that interview,” Couric said. “I don’t need a do-over. I’m very proud I was doing my job, and when someone is running for the second highest office in the land, I think it’s important to ask pointed, challenging questions, as I do for all candidates.”
