(CNN) – Former President George H.W. Bush remains in a Houston hospital Thursday after being treated for bronchitis, his spokesman said. His office said he was in stable condition.
Bush, 88, has been hospitalized at Houston's Methodist Hospital for six days and has a "lingering cough," spokesman Jim McGrath told CNN.

"President Bush has been in and out of The Methodist Hospital in the Texas Medical Center being treated for complications related to his bronchitis," his office said in a statement. "He is in stable condition, and is expected to be released within the next 72 hours."
Bush has a form of Parkinson's disease that affects his legs and requires him to use a wheelchair.
He is the oldest living former president and a World War II veteran.
He was previously hospitalized overnight in 2007 after a fainting spell caused by dehydration and hot weather while golfing in California.

Rest up, listen to your nurses and they'll have you up and about in no time! Thank you for your services to our country!
Best Republican President we have had in a long time. He had the foresight on Iraq and did not roll into Baghdad as many yearned for back then. He marshaled a vast international alliance to liberate Kuwait. He went back on Rad My Lips much to his demise but he did what was best for the country. What a patriot and great American. Get well soon President Bush.

Get well soon, Sir. You sure were right about Gulf War I (and this from a life long Democrat).

Since I'm a democrat, we have differences in ideology. However, any President of the United States, former or current, Republican or Democrat, deserves my respect. I hope you get well soon, Mr. President.
Read my lips. Get well!
Wishing you the very best. I am a diehard democrat but I have a great deal of respect for you. My hubby supported you in 1992, he has not supported another republican since. We hope you and your family can overcome this latest bump in the road. You were a fine President and a good man.
Get well soon!
