Veterans Administration hospitals have spent at least $420 million on solar panels and windmills while vets wait months — or even lay dying — to see a doctor.

In total, VA hospitals reported 23 deaths due to 76 instances of delayed care, an April 2014 VA fact sheet said. Then on June 5, Acting Veteran Affairs Secretary Sloan Gibson revealed that at least 18 Phoenix patients died while waiting for treatment on a secret list kept off the books. It is not clear if that number is in addition to the 23 deaths reported earlier. During the past month, the scandal has resulted in the resignations of both the VA secretary and the leaders of its health care component.

According to a June 3 audit, 100,000 veterans had lengthy wait times for appointments. Of the nation’s 216 VA hospitals, 37 percent will require further investigation.
