You apparently don't understand how the US system works. The person who speaks for American security services is the guy at the top of that service. No one else. Theoretically his entire service could hold one view, and he could come to a different one. That would be the position you would hear. He is a POLITICAL animal, appointed by the president and subject to being fired by him for any reason whatsoever.

Clapper is a proven liar, and an Obama appointee. FBI Director Comey personally screwed the Democrats in the days leading to the election by re-opening the investigation into Clinton's emails. (He'd closed the investigation only three months earlier.) Obama would have his head on a platter right now if not for Comey's act of contrition in vaguely accusing the Russians.

The naivety is in thinking that Washington politics is played honourably and above board.
