Hillary Clinton's campaign paid for research that 'helped fund Trump-Russia dossier'
Hillary Clinton's presidential campaign and the Democratic National Committee helped fund political research into President Donald Trump that ultimately produced a dossier of allegations about his ties to Russia, a source has said.
The revelation is likely to fuel complaints by Mr Trump that the dossier, which the president has derided as "phoney stuff", is a politically motivated collection of salacious claims.
Yet the FBI has worked to corroborate the document, and in a sign of its ongoing relevance to investigators, special counsel Robert Mueller's team - which is probing potential coordination between Russia and the Trump campaign - weeks ago questioned the former British spy, Christopher Steele, who helped compile the claims in the dossier.
The dossier, which circulated in Washington last year and was turned over to the FBI for its review, contends that Russia was engaged in a longstanding effort to aid Mr Trump and had amassed compromising information about him. Mr Trump has repeatedly dismissed the document as false and in recent days has questioned on Twitter whether Democrats or the FBI had helped fund it.
Mr Trump has also attacked the findings of the FBI, NSA and CIA that Russia waged a large-scale influence campaign to interfere in the election. The FBI and the CIA have said with high confidence that the effort was aimed at hurting Mrs Clinton's candidacy and helping Mr Trump. The NSA found the same with "moderate" confidence.
The source said the arrangement was brokered by Marc Elias, a lawyer for the campaign and the DNC, and his law firm of Perkins Coie.
The deal began in the spring of 2016, when the firm was approached by Fusion GPS, the political research firm behind the dossier, and lasted until right before election day, according to the source. When Fusion approached Mr Elias, it had already been doing research work on Mr Trump for a client during the GOP primary. The identity of the original client has not been revealed.
It is unclear what Fusion GPS had dug up by the time law firm hired them in April 2016. According to a copy of the dossier published by BuzzFeed last year, the earliest report from Mr Steele dates to June 2016, two months later. It was not immediately known how much money Fusion was paid or how many others in the Clinton campaign or DNC were aware that the firm had been retained.
Mr Elias did not immediately return an email seeking comment, and representatives of Fusion GPS declined to comment. The Washington Post first reported the arrangement.
Clinton campaign officials did not immediately comment, but in a statement, a DNC spokeswoman said chairman Tom Perez was not part of the decision-making and was unaware that Perkins Coie was working with Fusion GPS.
"But let's be clear, there is a serious federal investigation into the Trump campaign's ties to Russia, and the American public deserves to know what happened," the statement said.
Former Clinton campaign spokesman Brian Fallon said on Twitter that he regretted not knowing about Mr Steele's hiring before the election, and that had he known, "I would have volunteered to go to Europe and try to help him."
"I have no idea what Fusion or Steele were paid but if even a shred of that dossier ends up helping Mueller, it will prove money well spent," he wrote in another tweet.
According to a letter obtained by the AP on Tuesday night, representatives of Fusion GPS reached out to the firm in early March 2016 to express interest in continuing research on Mr Trump it had begun "for one or more other clients during the Republican primary contest".
At that time, the Clinton campaign was looking toward the general election and was pivoting attention toward Mr Trump, who was emerging as the Republican front-runner. The source said Mr Trump, by virtue of his extensive international business dealings, was seen as a natural target for complicated opposition research abroad.
Perkins Coie then engaged Fusion GPS in April 2016 "to perform a variety of research services during the 2016 election cycle," according to the letter.
The dossier created a political firestorm in January when it was revealed that then-FBI director James Comey had alerted Mr Trump to the existence of allegations about him and Russia. Since then, Mr Trump has repeatedly attacked it and Republicans in Congress have worked to discredit it, even issuing a subpoena to force the disclosure of Fusion GPS's bank records.
The letter, sent on Tuesday by the law firm's general counsel to a lawyer for Fusion GPS, was intended to release the research firm from its obligation to keep confidential the identity of its client.
