The office of former president George H.W. Bush has released a statement regarding the health of former first lady, Barbara Bush.
CNN, quoting a source close to the family, reported that Bush is suffering from Chronic Obstructive Pulmonary Disease (COPD), which makes it hard to breathe, and congestive heart failure. In years past she has been hospitalized for Graves' disease, a thyroid condition, and bronchitis, a respiratory ailment.
Barbara Bush, wife of the 41st president and mother of the 43rd, is said to be in "failing health".
McGrath said Mrs. Bush spent two days at Methodist Hospital earlier this month but decided not to return there when her health began to deteriorate.
U.S. Ambassador to the United Nations Nikki Haley tweeted Sunday that Bush is "a woman of great faith, great strength, and an unwavering love of country".
The statement continued that she appreciated the well wishes she had received and that her family is close to her.
