The day before the attack, Loudermilk led a tour of House offices.
The committee that oversees security at the Capitol could soon be led by him.
The most senior Republican lost his primary to a Trump supporter.
The committee that oversees Capitol security could be headed by Republican Barry Loudermilk of Georgia, who led the January 6 rioters on a tour of the Capitol.
Republicans are expected to regain control of the House in a few years. The second highest ranking Republican is Loudermilk. The committee is in charge of Capitol Police and security on the House side of the Capitol.
Miller had the support of Donald Trump and criticized Davis for voting to establish a bipartisan January 6 commission.
The January 6 committee released a video of Loudermilk leading a tour group through the House office buildings. At least one member of the tour group returned to the grounds of the Capitol the next day and yelled violent threats at the Democrats.
"When I get done with you, you're going to need a shine on top of that bald head," the attendee said in the video.
The man may have entered the Capitol building. The man and other tour attendees took photos of areas in the House office buildings that wouldn't normally be of interest to tourists.
Loudermilk claimed that the man was taking a photo of a golden eagle light fixture on the wall.
"Obviously, I do not support anything he said, but nobody in that group talked or spoke like that," said Loudermilk.
Loudermilk's story about the tours has changed many times. He pointed to a letter from Capitol Police that said they didn't consider any of the activities they observed to be suspicious.
Even though Loudermilk is next in line in terms of seniority, his position atop the committee is not certain; House Republican leadership is in charge of committee assignments for their members.
In a statement to Insider, Loudermilk said he would have to give serious consideration to chairing the committee if asked to do so by the next Speaker, but that his current focus is on the work the Republicans are doing on the Committee.
The Ranking Republican on the Committee on House Administration has done a great job. Loudermilk said that it has been an honor to work under his leadership. The decision on who becomes the chairman of the committee for the 118th Congress will be made by the speaker.
Facing criticism for appointing only white men to lead major committees, former Speaker John Boehner appointed a black man. She did not previously serve on the committee.
