“She will definitely have an elevated role and an amplified voice,” Rep. Jamie Raskin, D-Md., a member of the select committee, said in an interview.

He said Cheney speaks for millions of Americans, including Republicans, who are looking for answers to many lingering questions about Jan. 6. “She comes in with a lot of credibility and legitimacy,” he said…

But she has joined the Democrats on the Jan. 6 committee seamlessly, those members say, gaining trust that is rarely found across the political aisle, especially after the attack on the Capitol. She attends Zoom and in-person preparation meetings and has displayed an impressive level of commitment, knowledge and a “ferocious” work ethic.

“If you close your eyes, in our meetings, our Zooms, you wouldn’t be able to distinguish which voice she was,” committee member Rep. Pete Aguilar, D-Calif., said. “That’s the truth. We’re all talking about next steps and process and what we want to get out of this, and she’s been a committed partner in that.”
