not enough on its own but getting closer. page may be the victim of an effort to turn him into a spy, but he needs actually to have become one. maybe he did, but i don't think we know. yet.
the intelligence services may know. and of course he comes across poorly. but i try not to let my speculation run too far ahead of the evidence.
same with the susan rice thing. there's an allegation (probably made by the white house) but no evidence of wrongdoing. assuming it's the same story as the nunes thing, it's a second or third attempt to convert the trump-russia investigation into an unmasking story.
but the trump-russia story has legs. and the intelligence services are not going to be distracted from their investigation.
the one thing that seems to be universal: trump and his supporters all denied any links to russia and those links keep being revealed. it's the denials which make things look suspicious. it's good that the intelligence services are pursuing their enquiry in spite of white house obstruction.
i hope the senate brings susan rice into its investigation. i imagine she will have interesting things to say to the committee. maybe trump is trying to trash her in advance because he fears what she knows.
