Senate Judiciary Committee chairman Chuck Grassley said Thursday that he believes the committee's interviews with the witnesses of the Trump Tower meeting are complete, and that he hopes to officially release the transcripts as soon as possible.

Why it matters: Grassley said that Sen. Dianne Feinstein's unilateral release of the Glenn Simpson transcript "spooked" other witnesses, so the Trump Tower section of the investigation is now done. The witness transcripts Grassley hopes to release include interviews with Donald Trump Jr., Rinat Akhmetshin, Ike Kaveladze, Anatoli Samochornov and Rob Goldstone.
