Former US president Bill Clinton is in hospital in Washington DC after developing a fever.
Mr Clinton, 78, has been admitted to MedStar Georgetown University Hospital for “testing and observation”.
Angel Ureña, the 42nd president’s deputy chief of staff, told Sky’s US partner network NBC News he is in “good spirits and grateful for the care he is receiving”.
Another source close to Mr Clinton said the situation is “not urgent”.
“The former president will be fine,” the source added. “He developed a fever and wanted to be checked out. He is awake and alert.”

The former president, who served two terms from January 1993 until January 2001, also addressed the Democratic National Convention in Chicago this summer.
Since leaving office, he has undergone two heart operations in New York – having a quadruple bypass operation in 2004, and two stents inserted into a coronary artery in 2010.
He was also in hospital for six days in 2021 with a urological infection that spread to his bloodstream.
