President Donald Trump said Sunday he views his Ukrainian counterpart Volodomyr Zelensky as “calmer” and more interested in reaching a peace accord following their sit-down inside the Vatican this weekend.

The meeting between the two world leaders would have had the late Pope Francis "filled with hope," the last U.S. ambassador to the Vatican said.

Pope Francis's death at the age of 88 means the Catholic Church must choose a new leader. Here's how cardinals elect the next pontiff at the conclave.

Cardinal Kevin Farrell confirmed Pope Francis' d ied on April 21, the day after Easter, early in the morning. He was 88. Following the beloved pope's funeral, there will be a period of mourning before the selection process involving the governing body of the Vatican and the 135 cardinals eligible to participate in the conclave begins.
