Former President George HW Bush Moved Out of ICU; Barbara Bush Sent Home

The Bushes' 72-year marriage is the longest of any presidential couple.

— -- Doctors who are treating former President George H.W. Bush and his wife at a Houston hospital said today that the former president is out of the ICU and the former first lady has been discharged.

The couple released a photo and thanked supporters via the Twitter account of their post–White House spokesman, Jim McGraw.

Drs. Amy Mynderse and Clint Doerr, who have been treating the Bushes, answered reporters' questions about their medical treatment this morning.

At one point during the former president's stay, doctors inserted a breathing tube, and a ventilator was employed to assist his breathing. The tube was removed Friday, the doctors said, adding that he has been sitting up and watching television.

The couple's 72-year marriage is the longest of any presidential couple in U.S. history, according to The Associated Press.

"They're therapy for each other," Doerr said of the Bushes' interaction in the hospital.
