The Houston Methodist Hospital said in a statement yesterday that the medical team hopes to discharge him by the end of the week.
Bush, 92, was admitted to the hospital on April 14 due to a persistent cough. He was subsequently diagnosed with mild pneumonia, which his family spokesman Jim McGrath said has been treated and resolved.
McGrath had tweeted on Friday that Methodist decided to hold the former president over the weekend to ensure "a fully clean bill of health" before the Bushes leave for Maine soon.
