It may happen that Barack Obama and members of his administration are dragged before a grand jury and questioned under oath about what they knew about these break-ins, Roger Stone, former Trump adviser, told RT's Worlds Apart host, Oksana Boyko.

This week, President Trump demanded a probe into unsubstantiated allegations he made that former President Barack Obama ordered a wiretap on Trump Tower during the 2016 presidential campaign.

Roger Stone sat down with Oksana Boyko to talk about this latest bit of US political drama, as well as many other compelling issues.

On charges of Russia interfering in US elections

"I think it's important to note that the intelligence services here have yet to produce any evidence or proof whatsoever of Russian meddling in the American election. What we have are "allegations;" what we have are "projections" and "assessments." Let me review for you the assessments of the Central Intelligence Agency. They said there was no torture in American prisons during the Iraq War. That was a lie. They denied that there were renditions by foreign nationals by the US government during the Iraq War. That was a lie. They claimed that the attack on our mission in Benghazi was caused by a video that was shown one time in Turkey. That was a lie.
