Former New York City Mayor Rudy Giuliani has been hospitalized and is in critical but stable condition, according to a statement posted Sunday on X. 

Ted Goodman, a political strategist who launched a livestream program with Giuliani, posted about the hospitalization on Sunday evening.

“Mayor Rudy Giuliani is currently in the hospital, where he remains in critical but stable condition,” Goodman wrote. “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.

“We do ask that you join us in prayer for America’s Mayor Rudy Giuliani,” he added.

After learning the news, President Donald Trump called Giuliani the “Best Mayor” in New York City’s history.

“Our fabulous Rudy Giuliani, a True Warrior, and the Best Mayor in the History of New York City, BY FAR, has been hospitalized, and is in critical condition. What a tragedy that he was treated so badly by the Radical Left Lunatics, Democrats ALL — AND HE WAS RIGHT ABOUT EVERYTHING!” Trump wrote on Truth Social. “They cheated on the Elections, fabricated hundreds of stories, did anything possible to destroy our Nation, and now, look at Rudy. So sad!”

The hospitalization comes nearly eight months after Giuliani was seriously injured in a car crash in New Hampshire.

Fox News Digital learned at the time that Giuliani was flagged down by a woman fleeing a domestic-violence incident. The former mayor helped the woman and called 911, remaining at the scene until police arrived.

He later left the scene and was traveling on the highway when the vehicle he was riding in was struck from behind at a high speed. New Hampshire State Police said the crash happened just before 10 p.m. on Interstate 93 in Manchester.

Troopers and fire personnel were already on the southbound side handling the reported domestic-violence incident when they witnessed a two-vehicle collision on the northbound side. Both vehicles ended up in the median and were heavily damaged, according to police.

Giuliani’s head of security and spokesman, Michael Ragusa, told Fox News Digital at the time that he was in “good spirits and recovering tremendously.”

Giuliani was diagnosed with “a fractured thoracic vertebrae,” along with multiple lacerations and contusions and injuries to his left arm and lower leg, Ragusa said.

“This was not a targeted attack,” Ragusa added in a post on X.

“We ask everyone to respect Mayor Giuliani’s privacy and recovery, and refrain from spreading unfounded conspiracy theories.”
