Former mayor of New York City Rudy Giuliani remains in “critical but stable condition” in a Florida hospital, according to a spokesman.

“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,” said spokesman Ted Goodman in a statement. President Donald Trump said on Truth Social that Giuliani is “a True Warrior, and the Best Mayor in the History of New York City, BY FAR.”

The reason for the 81-year-old’s visit is unclear.
