FORMER U.S. President George H.W. Bush has been hospitalized with an infection, just after attending the funeral of his wife, Barbara, a spokesman said.

Jim McGrath said on Twitter on Monday that Bush, 93, is “responding to treatments and appears to be recovering.” He was admitted Sunday morning to Houston Methodist Hospital after an infection spread to his blood, McGrath said.

Barbara Bush was laid to rest Saturday in a ceremony attended by her husband and former presidents Bill Clinton, Barack Obama, George W. Bush and their wives, along with current first lady Melania Trump. She was 92, and she and her husband had been married 73 years – the longest presidential marriage in U.S. history.

The elder Bush uses a wheelchair and an electric scooter for mobility after developing a form of Parkinson’s disease, and he has needed hospital treatment several times in recent years for respiratory problems.

He attended the funeral wearing a pair of knitted socks decorated in blue, red and yellow books – a tribute to his late wife’s work promoting literacy.
