Former US President Gerald Ford has been taken to hospital in California, suffering from pneumonia.
Gerald Ford was never elected president
The 92-year old was admitted to the Eisenhower Medical Center on Saturday, according to his spokeswoman.
"He is doing well and resting comfortably," Penny Circle said in a statement on Monday, adding that he could be allowed home on Wednesday.
It is the second time in as many months that the former president has been admitted to hospital.
In December, he was taken to the same hospital to be treated for a bad cold.
As Vice-President, Gerald Ford became president in 1974 when Richard Nixon resigned because of the Watergate affair.
But he failed to win a full term in the 1976 presidential election, losing to Democrat Jimmy Carter.
Mr Ford remains the only US president never to have contested a national election before entering office.
