Rudy Giuliani rushed to hospital in critical condition

Known as ‘America's Mayor’

Writing on his platform Truth Social, Trump said: “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! They cheated on the Elections, fabricated hundreds of stories, did anything possible to destroy our Nation, and now, look at Rudy. So sad! President DONALD J. TRUMP”.

Meanwhile, the former mayor’s spokesman, Ted Goodman, said that Giuliani, 81, “remains in critical but stable condition”.

“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”, Mr Goodman said in a social media statement.

Why Giuliani was admitted to hospital or how long he has been there for has not been revealed.

He was elected New York's mayor in 1993 after serving as one of the nation's highest-profile prosecutors.

In 2000, he ran for the US Senate but abandoned his race against Hillary Clinton after being diagnosed with prostate cancer.

For helping unite the nation following the September 11 attacks in 2001, Giuliani earned the nickname “America's Mayor”.

He became a divisive political figure in recent years, as he served as an adviser and personal lawyer for Trump in his efforts to try to overturn the results of the 2020 presidential election.

Trump even pardoned Giuliani after he faced criminal charges in two US states and a defamation lawsuit from election workers.

Last year, in September the former New York City mayor was admitted to hospital after suffering a fractured vertebra and other injuries in a car crash in New Hampshire.
