Rudy Giuliani in critical condition

Rudy Giuliani is showing signs of a remarkable recovery after a life-threatening battle with severe pneumonia.

The 81-year-old former mayor and Trump advisor was hospitalized in Florida and placed on a ventilator last week, reaching a critical state where he reportedly received last rites.

His son, Andrew Giuliani, confirmed that his father is now 'cracking jokes' and has turned a corner in his health crisis.

The health scare has prompted an outpouring of support from political allies, while critics have reflected on his complex legacy in New York City.
