Former CIA director: I was concerned about 'interactions' between Russians and the Trump campaign

Former CIA Director John Brennan said that he was concerned by some interactions between Russian officials and members of the Trump campaign during testimony before the House Intelligence Committee. Following is a transcript of the video.

I encountered and am aware of information and intelligence that revealed contacts and interactions between Russian officials and US persons involved in the Trump campaign, that I was concerned about because of known Russian efforts to suborn such individuals, and it raised questions in my mind – again – whether or not the Russians were able to gain the cooperation of those individuals. I don't know whether or not such collusion – that’s your term – such collusion existed. I don't know. But I know that there was a sufficient basis of information and intelligence that required further investigation by the bureau to determine whether or not US persons were actively conspiring, colluding with Russian officials.
