Americans visiting Rome during conclave describe what they want in the next pope

The papal conclave is convening on Wednesday to begin the process of electing Pope Francis' successor. And for Americans who are visiting Rome this week, it's a chance to experience history.

"It's ... probably once-in-a-lifetime opportunity to be in Rome when they're doing the conclave," John Swierk told "CBS Mornings" co-host Tony Dokoupil.

Several Americans said they believe God will guide the conclave.
