VATICAN CITY, May 5 (Reuters) - U.S. Secretary of State Marco Rubio expects a "frank" meeting with Pope Leo during a visit to the Vatican this week, the U.S. ambassador said on Tuesday, after President Donald Trump took a fresh pot-shot at the pope for criticising the U.S. war in Iran.
"Nations have disagreements, and I think one of the ways that you work through those is ... through fraternity and authentic dialogue," said Brian Burch, the U.S. ambassador to the Holy See.
