Doctors in Houston will keep former U.S. President George H.W. Bush in a hospital through the weekend, though they "have begun discussing dates for his discharge," his office said Saturday.
Bush, 90, was taken by ambulance to Houston Methodist Hospital on Tuesday night and was admitted for observation after experiencing breathing difficulties earlier that evening, according to his spokesman, Jim McGrath.
There has been no word on whether the nation's 41st president is suffering from any particular ailment. McGrath said Wednesday that Bush's prognosis was positive and that he was being kept hospitalized as a precaution.
On Thursday, Bush received a Christmas Day visit from his wife, Barbara, as well as his son Neil and daughter-in-law Maria Bush. He was described as being in "great spirits."
"President Bush's condition has improved to the point that doctors have begun discussing dates for his discharge. He will remain at the Houston Methodist Hospital through the weekend for further observation," McGrath said Saturday.
George H.W. Bush was president from 1989 to 1993. He spent the previous eight years as Ronald Reagan's vice president.
His son, George W. Bush, served two terms as president beginning in 2001. Another son, Jeb Bush, is considering his own White House bid in 2016.
