Pope Francis was well enough to meet with the Vatican secretary of state to approve new decrees for possible saints, the Vatican said Tuesday, in announcing some major governing decisions that suggest he is getting essential work done and looking ahead despite being hospitalized in critical condition with double pneumonia.

Pope Francis "rested well throughout the night" in the hospital, the Vatican says, and even met with Vatican officials to sign several documents linked to sainthood designations on Monday.

Pope Francis was found to have pneumonia in both his lungs Tuesday and his condition remains "complex," the Vatican said in a health update on the 88-year-old pontiff who was hospitalized last week. The big picture: The pope was admitted to Rome's Agostino Gemelli Hospital on Friday with bronchitis symptoms and his treatment was changed after doctors found he had a polymicrobial infection of the respiratory tract.
