Bush family spokesman Jim McGrath made the announcement this morning.
The 88-year-old wife of former President George H.W. Bush has been at Methodist since Monday for treatment of pneumonia.
"I cannot thank the doctors and nurses at Houston Methodist enough for making sure I got the best treatment and got back to George and our dogs as quickly as possible," Mrs. Bush said in a statement released this morning.
Bush and her husband, the 41st president, live in Houston during the winter and in Maine during the warmer months of the year.
Their 69th wedding anniversary is this Monday.
