Input: The dossier  which is a collection of memos written over a period of months  includes specific  unverified  and potentially unverifiable allegations of contact between  Trump  aides and Russian operatives  and graphic claims of sexual acts documented by the Russians. BuzzFeed News reporters in the US and Europe have been investigating various alleged facts in the dossier but have not verified or falsified them. CNN reported Tuesday that a two-page synopsis of the report was given to President Obama and  Trump .
The document was prepared for political opponents of  Trump  by a person who is understood to be a former British intelligence agent. It is not just unconfirmed: It includes some clear errors. The report misspells the name of one company  "Alpha Group " throughout. It is Alfa Group. The report says the settlement of Barvikha  outside Moscow  is "reserved for the residences of the top leadership and their close associates." It is not reserved for anyone  and it is also populated by the very wealthy.
The  Trump  administration's transition team did not immediately respond to BuzzFeed News' request for comment. However  the president-elect's attorney  Michael Cohen  told Mic that the allegations were absolutely false.
And  Trump  shot back against the reports a short time later on Twitter.
