We begin today's show with a historic visit to the Vatican, where Britain’s King Charles and Queen Camilla met with Pope Leo. It’s the first time in 500 years that a British monarch has prayed with the Pope, a powerful gesture of reconciliation after centuries of conflict between Protestants and Catholics, and a symbolic encounter between the heads of the Church of England and the Catholic Church. CNN's Chrisopher Lamb, author of “The Outsider: Pope Francis and the Battle to Reform the Church," joins the show to discuss. 

Also on today's show: musician Annie Lennox; Sarah Leah Whitson, Executive Director, Democracy for the Arab World Now
