Former New York City Mayor Rudy Giuliani left the hospital Monday after undergoing treatment for injuries from a car crash in New Hampshire over the weekend, his son said.

“I’m happy to report that he got out of the hospital today. He’s walking, thank God,” the former mayor’s son Andrew Giuliani said on the “Cats & Cosby” radio show hosted by John Catsimatidis and Rita Cosby on WABC 770 AM.

The younger Giuliani said his father suffered a fractured vertebrae and “he’s in a lot of pain.”

“But as you guys know, there are few tougher than Rudy Giuliani, so I’m — and obviously, you hear this news here just about a half hour ago that President Trump is going to nominate him to become a Medal of Freedom recipient, is kind of overwhelming considering that, you know, just two days ago, I was — I was concerned whether or not he’d — we’d still have him with us or not,” he added.

The former New York City mayor, who later served as Trump’s personal attorney, was seriously injured in a car crash Saturday in New Hampshire, his security team said. Giuliani’s vehicle was hit “from behind at high speed,” his head of security Michael Ragusa said.

According to a statement, Giuliani was taken to a local trauma center “where he was diagnosed with a fractured thoracic vertebrae, multiple lacerations and contusions, as well as injuries to his left arm and lower leg.”

On Monday, President Trump announced that Giuliani would receive the Presidential Medal of Freedom, the country’s highest civilian honor, calling the former mayor “the greatest Mayor in the history of New York City, and an equally great American Patriot.”
