Rudy Giuliani, the former New York City Mayor and a long-time champion of President Donald Trump, is in a "stable but critical condition" in hospital, his spokesman Ted Goodman said in a social media post on Sunday.
Shortly after Goodman's post was published, Trump wrote on social media: "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."
He went on to praise Giuliani's efforts contesting the 2020 election results on his behalf, adding "he was treated so badly by the Radical Left Lunatics".
Goodman did not give further details. Giuliani was injured in a car accident late last year.
Giuliani became known as "America's Mayor" after leading New York City through the aftermath of the 9/11 attacks.
