Former New York City Mayor Rudy Giuliani, 81, is hospitalized in Florida with pneumonia, according to multiple reports citing his spokesman. Sources say he is in critical but stable condition. Initially, Giuliani was placed on a ventilator as part of his care, but his spokesman later said he is now breathing on his own. The update also indicates that clinicians continue monitoring him as a precaution.

Several outlets report that the pneumonia is connected to pre-existing respiratory issues and that his health history may have contributed to the severity of his illness. One report specifically says he developed a restrictive airway disease during his response to the Sept. 11, 2001 attacks, and that this condition helped worsen his pneumonia. Another outlet adds that his respiratory condition is described by his spokesperson as having left him vulnerable.

All sources agree on the core facts: Giuliani is hospitalized for pneumonia, remains in critical but stable condition, and is recovering while monitored in a hospital setting.
