A US congressional intelligence committee has released a report condemning intelligence whistleblower Edward Snowden for leaking information that "caused tremendous damage" to US national security nad urging President Barack Obama not to pardon him.
The House of Representatives intelligence committee issued the scathing report Thursday, saying that Snowden was "not a whistleblower" as he has claimed.  The report was endorsed by both its Republican and Democratic leaders.
Most of the material Snowden stole from the National Security Agency (NSA) while he worked at the spying agency was not about invasions of privacy, but disclosed intelligence and military programs of great interest to US adversaries, it said.
The report contains previously unreported allegations about Snowden and his possible motives for taking government secrets.
Snowden leaked thousands of classified intelligence documents in June 2013, revealing the extent of the NSA’s spying activities, including the massive collections of phone records of Americans and foreign nationals as well as political leaders around the world.
On Wednesday, several prominent human rights organizations urged Obama to pardon Snowden before leaving the White House in January.
However, the Obama administration has urged Snowden to return to the US and face trial, saying there is no doubt that he inflicted serious harm on the US national security.
His asylum in Moscow has been a source of tension between the US and Russia, with the US president canceling a planned meeting with Russian President Vladimir Putin at the G20 Summit in 2013 after Russia agreed to let him in.
