Bernie Sanders will be taking a few days off the campaign trail to attend a Vatican conference about social, economic and environmental issues.
The day after a debate in New York next week, Sanders will travel to Rome for the event.
In an interview on MSNBC's Morning Joe, Sanders said he was "a big, big fan of the pope."
"He has played an unbelievable role, unbelievable role in injecting a moral consequence into the economy," Sanders said. "He's talking about the idolatry of money, the worship of money, the greed that's out there."
