NBC Nightly News anchor Brian Williams sits down for an exclusive interview with former National Security Agency contractor Edward Snowden.
Williams has described the interview as "months in the making."
Last year, Snowden began leaking details of NSA spying programs and told Williams that he was "trained as a spy."
The revealing interview was conducted last week in Russia where Snowden has been granted temporary asylum.
The interview will air tonight at 10 p.m. on News10NBC.
