He said that seems much more likely than the report that a former Trump campaign adviser's drunken boasts - not the dossier - led to the investigation.
He said at the time BuzzFeed published the dossier on January 10, 2017, they knew it had been written by Christopher Steele, the former head of the Russian Federation desk for British intelligence, and that then-Senate Minority Leader Harry Reid (D-NV) and Senate Armed Services Committee Chairman John McCain (R-AZ) had "acted" on its contents.
A personal lawyer for US President Donald Trump has sued the news website BuzzFeed over the publication of a salacious dossier alleging collusion between the Trump team and Russian Federation.
BuzzFeed responded with a Twitter post saying the dossier continues to be the subject of investigations by Congress and intelligence agencies, was shown to two United States presidents and described in detail by news outlets worldwide. It was presented to two successive presidents, and has been described in detail by news outlets around the world.
Russian lawyer Natalia Veselnitskaya has given an exclusive interview to RT, sharing her analysis of the recently-released transcript of Fusion GPS' co-founder's testimony in the US Senate and the infamous "Trump dossier". "Its interest to the public is obvious", BuzzFeed spokesman Matt Mittenthal said via Twitter.
A spokesperson for BuzzFeed said in a statement to CNN, "This is not the first time Trump's personal lawyer has attacked the free press, and we look forward to defending our First Amendment rights in court".
"The Supreme Court has made it clear that when it comes to media-related publications on public figures, they are generally immune from defamation lawsuits unless they actually acted with malice".
Mr Cohen is named several times in the document and is of interest to congressional investigations into possible collusion with Moscow. "Why waste time talking about something that's not legitimate", he said.
In October, The Washington Post reported the Clinton campaign and the Democratic National Committee (DNC) had helped fund Fusion GPS' research on Trump's alleged ties with Russian Federation. Cohen said he has never been to Prague and his passport shows no visits to the Czech Republic. He used his network of contacts in east European intelligence services to examine Mr Trump's ties in Russian Federation for Fusion GPS, which was originally hired the candidate's Republican opponents.
House Intelligence Committee investigators got access to the remaining documents they had long sought as part of their Russian Federation inquiry during a classified session at the Justice Department on Friday, a source close to the matter told Fox News.
