Will there be more transcripts of unheard testimony?

While folks like former Attorney General Bill Barr have become a well-known witness for the committee, there’s an expectation we might hear more of their words than what’s been presented in hearings.
The panel also interviewed Trump’s daughter Ivanka Trump as well as former press secretary Kayleigh McEnany, which the committee noted in its introductory report they were not very cooperative.
Punchbowl News first reported based on an unnamed source familiar with a letter from the DOJ that the committee interviewed several prominent White House counsel members and lawyers for Trump, including former Attorney General Jeffrey Rosen, White House counsel Pat Cipollone, and more. All these transcripts were reportedly shared with the Justice Department.
