Pope Francis has been hospitalized since Feb. 14 with bilateral pneumonia, and it's making some question whether he'll step down from his duties.

Pope Francis has entered his fourth week in the hospital with double pneumonia. Francis has increasingly handed off his day-to-day duties to cardinals as questions swirl about the near- and long-term future of his papacy.

It marked the fifth Sunday in a row the Pope was not present in person for his weekly blessing, although the Vatican said earlier this week an X-ray had confirmed "improvements" in his condition. It has since cautioned he still needs hospital treatment.
