House Republicans are launching a vast re-investigation of the Jan. 6, 2021 attack on the Capitol, seeking to push the blame away from Donald Trump who has been indicted over his actions or his supporters in the mob siege trying to overturn the 2020 election.

As Trump campaigns to return to the White House, the House Administration subcommittee on Oversight held the first of what is expected to be regular public hearings revisiting the official account, which had aired in great detail in 2022 by the House’s Select Committee on Jan. 6.

Chairman Barry Loudermilk, R-Ga., called Jan. 6 a “dark day” in U.S. history as he opened Tuesday’s hearing to delve into the investigation of pipe bombs that were left outside Republican and Democratic party headquarters that day.

But he said, “we still have many unanswered questions.”
