"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", wrote Buzzfeed News spokesman Matt Mittenthal in an email to Vox News.
In the lawsuit filed last Tuesday in the NY state court, Cohen states that even though Buzzfeed claimed that the dossier had unverified information, they failed to clarify the reports with him. He provided the complaint and a confirmation email from the court system that he had filed the suit to Bloomberg News, but it could not immediately be independently confirmed that the suit had been filed.
However, as Fusion GPS founder Glenn Simpson's testimony before the Senate Judiciary Committee revealed, the Steele dossier was not the reason behind the FBI investigation. BuzzFeed later redacted its online version of the dossier to exclude those named and issued an apology shortly after the lawsuit was filed.
Josh Levy, a lawyer for Fusion, declined comment Wednesday morning.
Cohen has emerged as a figure of interest to congressional investigators probing Russian interference in the 2016 election.
Michael Cohen, a lawyer for President Trump, meets with Senate Intelligence Committee, Washington, 19 Sep.
In both complaints, Cohen alleges that the dossier contains "blatantly false and defamatory statements" that resulted in "harm to his personal and professional reputation, current business interests, and the impairment of business opportunities".
Smith made this argument in the op-ed: "I haven't had a single person approach me to say, 'I wish I hadn't read the dossier, and wish I had less insight into the forces at play in America.' Do you feel that way?" He said his name is mentioned 15 times. For example, that the Trump campaign chairman Paul Manafort hid payments for his work in Ukraine, as federal authorities have alleged; that the Russian diplomat Mikhail Kalugin was withdrawn suddenly from the United States; and that Mr. Trump sought, but never consummated, business deals in Russia. "I, like all Americans - Republicans and Democrats alike - want to know to what extent Russian Federation involved themselves in our democratic process, and more importantly what can be done to stop future involvement by foreign governments".
Fusion GPS was hired to conduct research into Mr. Trump during the 2016 presidential race.
As the seriousness of the Russian Federation investigation has become clearer, the pro-Trump line has shifted from dismissing the dossier to stressing its role in the investigation: The dossier, some of Mr. Trump's defenders now say, played too big a part, given that a portion of Mr. Steele's funding came from political enemies of Mr. Trump, including the Democratic National Committee.
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 is accused in the dossier of traveling to Prague in August 2016 as part of a collusion conspiracy between the Trump campaign and Russian government.
