(The Hill) — Rep. Liz Cheney (R-Wyo.) said Sunday that the House committee investigating the Jan. 6 riot is “fully prepared to contemplate a subpoena” for Virginia “Ginni” Thomas, the wife of Supreme Court Justice Clarence Thomas if she won’t testify before the committee voluntarily.

“The committee is engaged with her counsel. We certainly hope that she will agree to come in voluntarily but the committee is fully prepared to contemplate a subpoena if she does not,” Cheney told CNN “State of the Union” co-host, Jake Tapper. “I hope it doesn’t get to that. I hope she will come in voluntarily.”

Thomas has been under scrutiny for her political affiliations and communications with the Trump administration about overturning election results.

She attended the pro-Trump “Stop the Steal” rally just before rioters stormed the capitol, and she communicated with former White House Chief of Staff Mark Meadows and Trump attorney John Eastman to talk about overturning the 2020 presidential election results.

Cheney said Sunday that the committee has heard from “numbers of people who are similarly situated in terms of the discussions that she was having,” and stressed the importance of hearing Thomas’ testimony. 

Thomas reportedly said in early June that she was eager to appear before the panel, but her lawyer later said he didn’t see a need for her testimony.
