The Vatican says Pope Francis, who is hospitalized in critical condition with double pneumonia, was well enough to meet with Cardinal Pietro Parolin.

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' condition remains critical but stable and he was able to do some work while still in the hospital with double pneumonia, the Vatican said in a Tuesday evening update.
