A source close to King’s family confirmed his hospitalization to ABC News on Saturday.
King hosted “Larry King Live” on CNN for over 25 years and had been treated for lung cancer previously.
The talk show host has had some health struggles over the years, including a major heart attack in 1987 and an angioplasty in April 2019, ABC News reports.
King also lost two of his children last summer when his son, Andy, died of a heart attack in July and his daughter, Chaia, died of lung cancer in August.
He is being treated for COVID-19 at Cedars-Sinai Medical Center, according to ABC News.
