HOUSTON » Former President George H.W. Bush has been taken to a Houston hospital after experiencing a shortness of breath.

Spokesman Jim McGrath said in statement that Bush was taken Tuesday evening by ambulance to Houston Methodist Hospital as a "precaution."

McGrath says the 90-year-old Bush "will be held for observation."

Bush spent nearly two months in the same hospital and was discharged in January 2013 after treatment for a bronchitis-related cough and other issues.

Bush, who can no longer use his legs, most recently appeared at a November event with his son, former President George W. Bush.

The White House says President Barack Obama, who is vacationing in Hawaii, has been notified about Bush’s admission.

White House spokesman Eric Schultz says the president and first lady "send their good wishes" to Bush and his family.
