GOP's Grassley refused to release testimony.

Senate Judiciary Committee Ranking Member Dianne Feinstein (D-Calif.) has released the transcript of Glenn Simpson’s testimony before the Senate Judiciary Committee.

Simpson is the co-founder of Fusion GPS, which compiled the so-called Steele Dossier on Donald Trump.

“After speaking with majority and minority committee staff for 10 hours, Glenn Simpson requested the transcript of his interview be released publicly. The American people deserve the opportunity to see what he said and judge for themselves,” said Feinstein.

“The innuendo and misinformation circulating about the transcript are part of a deeply troubling effort to undermine the investigation into potential collusion and obstruction of justice. The only way to set the record straight is to make the transcript public.”

She has the support of committee Democrats.
