"Whatever else Snowden believes he has done, its hard to deny that yesterday he was a prop for Vladimir Putin in a Russian Federation infomercial," Hayden said of the appearance, adding, "What could have motivated him to do that?"
Snowden went to Moscow after being charged under the espionage act last June.
On Twitter Thursday, Glenn Greenwald, the reporter who published many of the first stories based on Snowden's leaked NSA documents mocked those who would criticize his appearance with Putin.
"Snowden should storm the Kremlin, take their surveillance docs & demand to be sent to the US: just like his brave patriotic critics would do," Greenwald wrote.
Snowden wrote an op-ed Friday in The Guardian, explaining he went on television with Putin to ask the Russian leader in order to publicly question his surveillance practices.
