Former U.S. National Security Agency (NSA) contractor Edward Snowden has rejected a scathing report issued by a U.S. House committee.
The House Intelligence Committee report on September 15 accused Snowden of leaking secrets that "caused tremendous damage" to U.S. security.
The report also declared that Snowden was "not a whistle-blower" as he has claimed in interviews, and that most of the material he stole from the NSA was about intelligence and defense programs of great interest to U.S. foreign adversaries.
The report comes a day after two rights groups launched a campaign for U.S. President Barack Obama to pardon Snowden. The White House has rejected the pleas.
In a series of tweets, Snowden dismissed the findings of the report.
"Their report is so artlessly distorted that it would be amusing if it weren't such a serious act of bad faith," he wrote on Twitter.
The report coincides with the release of Snowden, a movie directed by Oliver Stone, which portrays Snowden as a whistle-blower and hero.
