'Human source' in Trump orbit contacted FBI, Fusion GPS co-founder told senators

Fusion GPS co-founder Glenn Simpson, whose firm commissioned a controversial dossier alleging secret ties between President Donald Trump and the Kremlin, told congressional investigators in August that the FBI found the dossier credible because an unnamed "human source" associated with Trump had offered the bureau with corroborating information. In a 312-page transcript of Simpson's August 2017 interview with the Senate Judiciary Committee, Simpson's attorney also said it was dangerous to discuss the dossier's sources because its public release in 2017 had already led to murder. "Somebody's already been killed as a result of the publication of this dossier and no harm should come to anybody related to this honest work," said the lawyer, Joshua Levy.

The transcript was released unexpectedly Jan 9 by committee Ranking Member Dianne Feinstein (D-CA), angering the committee's Republican Chairman Charles Grassley (R-IA). Ranking Member Feinstein's decision to publish the dossier represents an escalation of partisan tensions that have long been simmering on the Senate Judiciary Committee. Simpson had called for the transcript of his appearance to be made public, but Republican leaders so far had not agreed to release it. A spokesman for Chairman Grassley said Feinstein posted the transcript with "no agreement" from committee Republicans.
