An associate of Donald Trump expressed concerns to the FBI about contacts between Russia and Trump’s presidential election campaign team, helping to trigger the probe into possible collusion, according to closed-door testimony made public on Tuesday by a senior Democrat. Glenn Simpson, who leads the Washington research firm Fusion GPS, said in his August testimony that the Federal Bureau of Investigation received intelligence from a “voluntary source” in Trump’s orbit in 2016, before a former British spy gave the FBI his own “dossier” of allegations about collusion. Fusion GPS hired the former spy, Christopher Steele, to investigate Trump’s business dealings with Russia.
Some Republicans critical of Special Counsel Robert Mueller’s probe into possible collusion between the Trump campaign and Russian officials have claimed the initial FBI probe was triggered by Steele’s dossier.
They have raised questions about whether the FBI may have relied on the Steele document to improperly obtain surveillance warrants to spy on Trump’s campaign associates.
Simpson’s testimony before the Senate Judiciary Committee in August contradicted those claims.
