In an interview on NBC's The Today Show, Republican operative Roger Stone addressed accusations of Russian collusion to help Donald Trump get elected president. Stone also spoke about the firing of FBI Director James Comey and Trump's "potential to be a transformational president." The Trump confidant told the NBC morning show he "was under surveillance for some period" in regards to Russia. "Since members of both of [the House and Senate Intelligence] committees have disparaged me in public, I'd like the opportunity to testify in public," he said. "I have no legal jeopardy. The idea of Russian collusion is a canard. It's a falsehood." "The Russian collusion scandal is a scandal without evidence to this day. There is still no evidence that would ever hold up in a U.S. court of law," Stone said Thursday morning. "I at least know what's in my emails. And I know what's in my texts. And I know what the context of my phone calls are. And I believe that I was under surveillance for some period." Stone was asked by co-host Matt Lauer if he was 'elated' by Comey's firing. "Yes, that's fair to say," Stone replied. Replying to accusations that he was instrumental in talking Trump into firing Comey, Stone said he has spoken to Trump "fairly recently, but not yesterday." "I do think he needed to go," Stone said of Comey. "I think the president did the right thing. I think he became unaccountable." "I am a loyal supporter of Donald Trump. I think he has the potential to be a transformational president. I'm not going to contradict him here on the 'Today Show.' I think in the case of James Comey, he made the right decision," he said.
