The Air Force and the White House last week in interviews with UPI said the allegations were misleading.
White House spokesman Trent Duffy referred UPI to the Air Reserve Personnel Center in Colorado where Technical Sgt. Rob Mims is the spokesman.
Mims said the claims were "not true. I verified that (Thursday). Lieutenant Bush received Air Force Outstanding Unit Award while he was in basic training with the 3724th Basic Military Training Squadron at Lackland Air Force Base, Texas."
Starr sent UPI a copy of a file of his research, including correspondence he had with the Air Force seeking to obtain the service records of Bush.
"This means, beyond a shadow of a doubt, that George W. Bush was photographed wearing a ribbon he clearly did not earn," wrote Starr. He said awards earned by the unit were given before Bush joined the unit.
Mims said that personnel records in the military are often incomplete due to "clerical errors."
"But I did verify that that unit did get the award while he (Bush) was there," said Mims.
The sergeant added that the photo in question was "taken after pilot training."
Mims said he confirmed his information about the medal with the Air Force's history office.
"It's all there in black and white, we've spelled it out," said Mims.
