Moscow, December 15 (RHC)-- Former U.S. intelligence contractor Edward Snowden says he is not worried about his fate and future under US President-elect Donald Trump, who assumes office in January. 

"I'm not worried," Snowden said in an interview with Twitter, when asked if he is worried a Trump presidency could lead to his imprisonment. "I'm comfortable with the decisions that I made and believe that I did the right thing."  He noted that: "If my own personal security was the only thing I cared about I would have never come forward and done all this." 

There are concerns that the possible mending of ties between Moscow and Washington under the president-elect would lead to Snowden's extradition to the U.S. and serve time in jail. 

Snowden began leaking classified intelligence documents in June 2013, revealing the extent of the National Security Agency (NSA)'s spying activities, including the massive collections of phone records of Americans and foreign nationals as well as political leaders around the world. 

After the move, U.S. authorities charged Snowden with espionage and theft of state secrets and documents.  Snowden is currently wanted by the U.S. government for treason and faces up to 30 years in prison.  Many people around the world, however, consider him a hero who did what was morally correct and benefited the public. 

In 2013, Snowden fled to Russia and was granted temporary asylum there.  His asylum in Moscow has been a source of tension between the US and Russia, with U.S. President Barack Obama canceling a planned meeting with Russian President Vladimir Putin at the G-20 Summit in 2013 after Russia agreed to let him in.
