Sen. Mike Lee (R-UT) is questioning what members of the former House select committee investigating Jan. 6 hid about the riot after Speaker Mike Johnson (R-LA) began releasing security footage from the day to the public.

Lee, in a series of posts on X (formerly known as Twitter), questioned the work of the now-dissolved committee, specifically the two House Republicans on it — former Wyoming Rep. Liz Cheney and former Illinois Rep. Adam Kinzinger — and called for an investigation.

"Why didn’t Liz Cheney and Adam Kizinger ever refer to any of these tapes? Maybe they never looked for them. Maybe they never even questioned their own narrative. Maybe they were just too busy selectively leaking the text messages of Republicans they wanted to defeat," Lee said in a post featuring footage released on Friday.

Lee went on to say in follow-up posts that "we need to investigate the J6 committee" and "taxpayer dollars funded the sham J6 committee." He then questioned whether information about the committee's work was "deliberately lost or destroyed."

The Utah Republican also replied to a tweet from Cheney where she shared footage of the riot outside the Capitol.

"Liz, we’ve seen footage like that a million times. You made sure we saw that—and nothing else. It’s the other stuff—what you deliberately hid from us—that we find so upsetting. Nice try. P.S. How many of these guys are feds? (As if you’d ever tell us)," Lee said.

Cheney responded by quipping that "a nutball conspiracy theorist appears to be posting from" Lee's account.

The House Select Committee on the January 6 Attack was disbanded at the conclusion of the 117th Congress in January 2023 after releasing its final report in December 2022. The committee was made up of seven Democrats and two Republicans, all of whom were appointed by then-House Speaker Nancy Pelosi (D-CA).

Kinzinger did not seek reelection in 2022, while Cheney lost to GOP challenger, now-Rep. Harriet Hageman (R-WY) in the 2022 primary by nearly 40%.

The release of the Jan. 6 security tapes was spearheaded by Johnson, who said the footage was to allow people to make their own conclusions on the events of the day.

"This decision will provide millions of Americans, criminal defendants, public interest organizations, and the media an ability to see for themselves what happened that day, rather than having to rely upon the interpretation of a small group of government officials," Johnson said in a statement on Friday.
