WASHINGTON (Circa) -- Former President George H.W. Bush has been hospitalized and is in intensive care, according to CNN.
Bush went to the hospital just hours after the funeral of former first lady Barbara Bush.
She passed away at the age of 92 last week.
In her honor, Bush wore a pair of socks with books printed on them. His wife was an advocate for literacy.
The former President's spokesperson wrote in a tweet that Bush wanted to honor his wife's commitment to literature and the $110 million she raised over the course of 30 years on behalf of the cause.
The 41st president attended the ceremony using a wheelchair and electric scooter to get around. George W. Bush pushed his father into the service and assisted him throughout the funeral.
Bush took time to greet mourners who gathered to pay their respects to his wife on Friday. Over 5,000 people were in attendance for Saturday's funeral.
The office of George H.W. Bush released the following statement:
"President Bush was admitted to the Houston Methodist Hospital yesterday morning after contracting an infection that spread to his blood. He is responding to treatments and appears to be recovering. We will issue additional updates as events warrant."
On Saturday, during the funeral of Barbara Bush, the former President took a picture that went viral alongside his son former President George W. Bush, current first lady Melania Trump, former President Barack Obama and former first lady Michelle Obama, and former President Bill Clinton with former Secretary of State and first lady Hillary Clinton.
A year ago this month, Bush spent two weeks in the hospital for treatment of pneumonia and chronic bronchitis, a constant irritation of the lining of tubes that carry air to one's lungs. Bush's doctors said chronic bronchitis is a condition more prevalent with age and can aggravate the symptoms of pneumonia.
Bush was hospitalized for 16 days in January 2017 for pneumonia. During that hospital stay, which included time in intensive care, doctors inserted a breathing tube and connected him to a ventilator.
He also was hospitalized in 2015 in Maine after falling at home and breaking a bone in his neck, and in December 2014 for about a week for shortness of breath. He spent Christmas 2012 in intensive care for a bronchitis-related cough and other issues.
George Herbert Walker Bush served as president from 1989 to 1993. Born June 12, 1924, in Milton, Massachusetts, Bush also served as a congressman, CIA director and Ronald Reagan's vice president.
