Rudy Giuliani, the former New York City mayor and attorney for Donald Trump, has been hospitalized and is in critical condition, his spokesperson confirmed Sunday evening.

Ted Goodman, Giuliani's spokesperson, described the 81-year-old's condition as "critical but stable" in a statement posted on social media. "Mayor Giuliani is a fighter who has faced every challenge in his life with unwavering strength, and he's fighting with that same level of strength as we speak," Goodman said.

The spokesperson requested prayers for Giuliani, referring to him as "America's Mayor," but did not provide details about the cause of his hospitalization or specify which medical facility he is being treated at. Multiple news outlets reported that Giuliani is hospitalized in Florida.

Giuliani served as New York City's mayor from 1994 to 2001 and gained national prominence for his leadership during the September 11, 2001 terrorist attacks. In recent years, he has worked as Trump's personal attorney and played a prominent role in challenging the results of the 2020 presidential election.

No additional details about Giuliani's medical condition or prognosis have been released. The former mayor's representatives have asked for privacy during this time while supporters have been encouraged to keep him in their prayers.
