This is not to suggest that what is said on the brief video is illegal or inappropriate. It isn't, at all. It just is to point out that Carter Page did not pop up on the FBI radar by pure chance because of the Steele Dossier.
Not that there's anything wrong with evidence popping up in the Steele Dossier, mind you, none of which has yet been refuted and much of which has been validated already. But sometimes you don't need such things to make a far-larger point.
