SCIUTTO: We're just one day away from the start of President Trump's Senate trial. Senators will sit to decide whether to remove him from office. The lead impeachment manager, Intelligence Chairman Adam Schiff claims that U.S. Intelligence agencies are stonewalling potentially important evidence for the trial.</s>REP. ADAM SCHIFF (D-CA): The intelligence community is beginning to withhold documents for Congress on the issue of Ukraine. They appear to be succumbing to pressure from the administration, the NSA in particular is withholding what are potentially relevant documents to our oversight responsibilities on Ukraine, but also withholding documents potentially relevant that the senators might want to see during the trial.</s>SCIUTTO: Joining me now to discuss is Shawn Turner; he's former director of communications for U.S. national intelligence, and Jeff Mason; White House correspondent for "Reuters", thanks to both of you. Shawn, let me ask you based on your experience. What kind of evidence is the NSA and other intelligence agencies required to share with the relevant committees, in this case, the house Intelligence Committees. And I'm just curious. Can you think of a time during your tenure that the Intel agencies refused a congressional request?</s>SHAWN TURNER, FORMER DIRECTOR OF COMMUNICATIONS FOR U.S. NATIONAL INTELLIGENCE: Well, I certainly can't remember a time when the Intelligence agency would have refused a request as long as their request was consistent with the Intelligence Committee's -- Oversight Committees. And to be candid, Jim, I'm not sure, that that's what's happening here. Look, as the chairman of the House Permanent Select Committee on Intelligence, Adam Schiff understands that it is certainly -- potentially, it's certainly possible that in the course of typical foreign intelligence collection activities by the NSA, that there may have been information, documents or conversations that could have potentially been collected between foreign individuals outside of the United States that could potentially be related to the impeachment proceedings. And, so he's asking the right questions. END
