I think Carter Page is probably under some kind of non-disclosure agreement for his FBI work and isn't allowed to talk about it in front of the cameras.
He might not have realized the feds were using him to dirty up Trump's campaign and it's possible that he's wibbling in front of the camera because he wants to tell the truth but isn't allowed to. (Hell they might even be blackmailing/threatening him on the side) If he's dirty and with the cabal he can burn in hell, otherwise he might be one of the puzzle pieces who can reveal the truth going forward.
