Grieving George Bush taken to hospital with an infection
Former US president George HW Bush has been taken to hospital in Houston with an infection, just after attending the funeral of his wife, Barbara, a spokesman said.
Jim McGrath said on Twitter that the 93-year-old is "responding to treatments and appears to be recovering".
He was admitted on Sunday morning to Houston Methodist Hospital after an infection spread to his blood, Mr McGrath said.
The elder Bush uses a wheelchair and an electric scooter for mobility after developing a form of Parkinson's disease.
He has needed hospital treatment several times in recent years for respiratory problems.
