"President @GeorgeHWBush was discharged from @MethodistHosp after treatment for an infection. His doctors report he is doing well and is happy to return home," McGrath tweeted.
On April 22, the 93-year-old was admitted to the Intensive Care Unit (ICU) after contracting the life-threatening infection that spread to his blood, just days after the death of his wife Barbara.
He was later shifted to a regular patient room at the hospital.
Bush's wife and the former US first lady, Barbara Bush passed away on April 17 in Houston, at the age of 92.
Bush, a Republican, served as the 41st US President from 1989 to 1993. He also served as the 43rd US Vice-President from 1981 to 1989.
His eldest son, George W. Bush also served two terms as the 43rd US President from 2001 to 2009. (ANI)
