Former New York mayor Rudy Giuliani was hospitalized with pneumonia and remains in “critical but stable condition,” his spokesman said in a statement Monday.

Giuliani, 81, initially was placed on a ventilator “to maintain adequate oxygen and stabilize his condition,” his spokesman, Ted Goodman, said in the statement. As of late Monday morning, Goodman said, the former mayor and longtime ally of President Donald Trump had been taken off the ventilator and “is now breathing on his own.”
