Former US president George HW Bush has been taken to hospital, according to local media reports.
The 92-year-old is said to be in a stable condition and is “doing fine”, his chief of staff, Jean Becker, told KHOU 11 News.
She said he was expecting to return home in a few days but did not give details about why the former commander-in-chief is being looked after at Houston Methodist Hospital in the Texas Medical Center.
It is understood Mr Bush – the 41st president of the United States from 1989 to 1993 – was not expecting to attend Donald Trump’s inauguration on Friday due to his health.
He has twice before been admitted to the same hospital.
Mr Bush spent two months there in November 2012 for bronchitis and was admitted again in November 2014 for breathing problems.
He received treatment at a hospital in Maine in 2015 after falling at his summer home and breaking a bone in his neck.
He is the father of former president George W Bush and ex-Florida governor Jeb Bush, who sought the 2016 Republican presidential nomination.
