The top Democrat on the Senate Judiciary Committee has released a transcript from an interview with the co-founder of Fusion GPS, the firm that commissioned a dossier of allegations about President Donald Trump's ties to Russia.
California Sen. Dianne Feinstein released the transcript from an August closed-door committee interview with Glenn Simpson after the Republican chairman of the committee, Iowa Sen. Chuck Grassley, declined to.
Feinstein's move comes a day after two other committee Democrats, Sens. Richard Blumenthal and Sheldon Whitehouse, sent a letter to Grassley asking him to release the transcript.
Simpson's firm commissioned the dossier, which was initially paid for by a conservative website and later by Democrats.
The dossier was written by former British MI6 agent Christopher Steele.
Trump has derided the dossier as politically motivated, and several GOP-led committees are investigating whether it formed the basis for the FBI's initial investigation into Russian election interference.
Democrats says those investigations are a distraction.
