VATICAN CITY — Cardinals wrapped up their pre-conclave meetings Tuesday, trying to identify a possible new pope who could follow Pope Francis and make the 2,000-year-old Catholic Church credible and relevant today, especially to young people.

Roughly a week after Donald Trump started his second term as president, the U.S. military issued an order to three freight airlines operating out of Dover Air Force Base in Delaware and a U.S. base in Qatar: Stop 11 flights loaded with artillery shells and other weaponry and bound for Ukraine.

Two cardinals, Michael Czerny and Chibly Langlois, sat down with ABC News to discuss the challenges facing the church that the new pope will have to face.
