Former president George H.W. Bush has been hospitalized in Houston since Saturday, a Bush family spokesman confirmed on Wednesday.

According to reports, the 92-year-old was admitted to Methodist Hospital in the Texas Medical Center for "shortness of breath," and is "responding very well" to treatments.

He is expected to be released in a couple of days.

"He's there. He's fine and he's doing really well," Bush chief of staff Jean Becker told the Houston Chronicle.
