26 officials, senior members of the Obama Administration, and members of the oversight committees of Congress do not view Snowden as a hero or even an authentic whistle-blower. Instead they see him as a betrayer of secrets who, acting willfully brought damage to the United States and benefits to its adversaries. The holders of this darker view of Snowden base it on classified reports of the full extent of the theft of classified data. Those officials reckon that only handful of the tens of thousands of documents he stole involved domestic surveillance, and these few documents served as a cover for a much larger theft. Admiral Michael Rogers, who replaced General Alexander as head of the NSA in January 2014, said that March at a public forum at Princeton University. “Edward Snowden is not the "whistleblower" some have labeled him to be.” He further explained to Congress: “Snowden stole from the United States government a large amount of classified information, a small portion of which is germane to his apparent central argument regarding NSA and privacy issues.” Gen.

The Defense Department loss in terms of the number of files stolen actually exceeded the loss, in sheer numbers, o
