But the dossier's author, Steele, wasn't brought into the mix until after Democrats retained Fusion GPS.
Washington Post reporters Tom Hamburger and Rosalind S. Helderman explain the story behind a controversial dossier on President Trump.
The revelation is likely to fuel complaints by Trump that the dossier, which the president has derided as "phony stuff", is a politically motivated collection of salacious claims. "But let's be clear, there is a serious federal investigation into the Trump campaign's ties to Russian Federation, and the American public deserves to know what happened", the statement reads.
Between June 2015 to December 2016, the Clinton campaign paid Perkins Coie $5.6 million in legal fees, according to campaign finance records examined by the Washington Post. It then outlined what Fusion GPS could disclose.
'For instance, it could have been that a decision was made to authorize Perkins Coie to commission do some kind of, commission some kind of research but then decisions about going out and finding Fusion GPS, finding Christopher Steele, I mean she may or may not have been aware of that level of detail I don't know, ' he said. The DNC and Clinton campaign engaged Fusion in April to "perform a variety of research services during the 2016 election cycle".
Earlier Tuesday, Fusion GPS lawyer William Taylor issued a statement that Congress' request was overly broad and that it was "designed to punish President Trump's political foes while chilling future investigative research into his actions".
Congressional investigators have accused the firm's president, Glenn Simpson, a former reporter, of stonewalling their investigation by refusing to say who paid for it and what their motives were.
They argued that committee staffers had "systematically disclosed confidential and prejudicial information" about Fusion.
Some of Steele's allegations began circulating in Washington, D.C.in the summer of 2016 as the FBI launched its counterintelligence investigation into possible connections between Trump associates and the Kremlin.
Citing Fox News, Trump tweeted Wednesday morning, "Clinton campaign & DNC paid for research that led to the anti-Trump Fake News Dossier". Fusion GPS has said in court filings that it did not give Buzzfeed the document. Steele is widely respected in intelligence circles and spent time working in Moscow under diplomatic over toward the end of the Cold War.
The dossier helped fuel the ongoing investigations into Trump and Russian Federation, including the special counsel probe led by Former FBI Director Mueller. The infamous Trump dossier that alleges the president had ties to Russian Federation and served as part of the reason why we have a special counsel-Robert Mueller-looking into such allegations turned out to be a DNC-funded operation.
Trump tweeted on Saturday that the Federal Bureau of Investigation and Justice Department should "immediately release who paid for it" after Fusion GPS co-founder Peter Fritsch and partner Thomas Catan last week invoked the US Constitution's Fifth Amendment, which protects Americans against self-incrimination.
Over objections from Democrats, the Republican leader of House Intelligence Committee, Rep. Devin Nunes (Calif.), subpoenaed Fusion GPS's bank records in order to try to identify the mystery client.
