"There is a Russia investigation without a dossier ... So to the extent the memo deals with the dossier and the FISA process, the dossier has nothing to do with the meeting at Trump Tower. The dossier has nothing to do with an email sent by Cambridge Analytica. The dossier really has nothing to do with George Papadopoulos' meeting in Great Britain. It also doesn't have anything to do with obstruction of justice. So there's going to be a Russia probe, even without a dossier."
