New York City's former mayor Rudy Giuliani is in critical condition in hospital, Donald Trump has said in a post on his Truth Social platform.
"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," the US president said.
"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."
Mr Giuliani's spokesman Ted Goodman said the 81-year-old "remains in critical but stable condition".
He did not say why he is in hospital or how long he has been there for.
"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 statement on social media.
Giuliani was elected New York's mayor in 1993 after serving as one of the nation's highest-profile prosecutors.
He ran for the US Senate in 2000 but abandoned his race against Hillary Clinton after being diagnosed with prostate cancer.
