DENVER — New criticism of the VA's troubled hospital construction program turned up the pressure in Congress on Friday for the agency to turn over future big projects to the Army Corps of Engineers. Senate Veterans Affairs Committee Chairman Johnny Isakson said a series of reports by the Corps of Engineers reinforces the need for the Veterans Affairs Department to stay out of construction and "and focus on the business of providing care to veterans." The VA asked the Corps to look at what went wrong with hospitals in Aurora, Colorado; Orlando, Florida; North Las Vegas, Nevada; and New Orleans.
