Wahl said that RT "whitewashes the actions of [Vladimir] Putin" and that she could no longer be a part of the channel. In a statement, RT derided the resignation as a "self-promotional stunt."
Speaking to Cooper, Wahl said that "the propagandist nature of RT came out in full force" in its coverage of the battle over Crimea.
"I would hope as a reporter and in life, you should always seek the truth, spread the truth, disseminate the truth," she said. "And what's clear is what's happening right now amid this crisis is that RT is not about the truth. It's about promoting a Putinist agenda."
