- The former president was previously hospitalized this year
- His spokesman said he was being held for further observation
"Mr. Bush had a good night's rest, and his spirits are high," Bush spokesman Jim McGrath said in a statement Wednesday. "Although he will not be discharged today, he is already looking forward to going home to Mrs. Bush, who has been constantly by his side."
McGrath confirmed the return to the hospital Tuesday, adding that Bush was admitted due to a cough that prevented him from sleeping. The cough turned out to be due to pneumonia, which has been treated and resolved, McGrath said. Bush remains under observation at Houston Methodist Hospital.
"President Bush is in very good spirits and is being held for further observation while he regains his strength," the statement read.
A source close to Bush told CNN's Jamie Gangel the former President was receiving IV antibiotics and will probably be kept at the hospital for a few more days for observation. The source said the Bushes had not previously announced the hospital visit because they did not want to worry anyone over the Easter weekend.
Bush was last admitted to Houston Methodist Hospital in January
to address "an acute respiratory problem stemming from pneumonia" before being released from the hospital on January 30.
Bush's wife, former first lady Barbara Bush, was hospitalized in January over bronchitis before being released the same month.
Just five days after his release from the hospital, Bush tossed the coin alongside his wife at the 2017 Super Bowl in Houston.
Former President Bill Clinton visited Bush earlier this month
and gave him a few pairs of patterned socks.
