The DoD IG conducted an investigation and released
a report less than three weeks ago. It didn't receive much attention from the media because the blame could not be placed on Trump.
I'm sure the typical handwaving, blame shifting and TDS used to dismiss the report will reach the same levels of hilarity as used to diismiss and ignore the DOI IG report.
I know what news station you get your info from so you might have missed it

, but this was reported by CNN, NBC, CBS, ABC, MSNBC etc quite extensively.
"I'm sure the typical handwaving, blame shifting..." You mean like the GOP Congress members and Trump supporters who handwaved away and blame shifted what happened on Jan. 6? Mo Brooks, Sarah Palin, and Matt Gaetz suggested it was probably Antifa that were the rioters and not Trump supporters. Here a few of those GOP Congress members who are guilty of this nonsense:
Rep. Andrew Clyde of Georgia: “Watching the TV footage of those who entered the Capitol and walked through Statuary Hall showed people in an orderly fashion staying between the stanchions and ropes, taking videos and pictures. You know, if you didn’t know the TV footage was a video from January the 6th, you would actually think it was a normal tourist visit.” He also said "“Let’s be honest with the American people — it was not an insurrection, and we cannot call it that and be truthful."
Rep. Jody Hice of Georgia: “It was Trump supporters who lost their lives that day, not Trump supporters who were taking the lives of others." She claimed Dems were "cherry-picking" Trump's words on 1/6. I guess she forgot that many rioters said they were there
because Trump asked them to come to "Stop the Steal."
Rep. Paul Gosar of Arizona: "The DoJ is harassing peaceful patriots across the country" (referring to the investigation of 1/6 rioters). "Who
executed Ashli Babbitt? (He made sure to first mention that Babbitt was unarmed, wrapped in an American flag, a veteran, and then "referred to her death as a homicide.") He also tried to downplay it because no guns had been confiscated in spite of the fact that many insurrectionists came armed with knives, sprays of various sorts, baseball bats, etc. " He claimed that "outright propaganda and lies are being used to unleash the national security state against law abiding U.S. citizens, especially Trump voters.”
Ron Johnson of Wisconsin: "They're concentrating on a false narrative. And that false narrative was that there were thousands of armed insurrections (sic). There weren't, But I condemned the breach. I condemned the violence." And "“By and large, it was a peaceful protest, except for there were a number of people, basically agitators that whipped the crowd and breached the Capitol. That's really the truth of what's happening here.”
Ralph Norman of S. Carolina: “I don't know who did a poll to say that they were Trump supporters." (Maybe the Trump flags, MAGA hats, and the rioters own statements confused Mr. Norman.)
Marjorie Taylor Greene of Georgia: “One person accused faces seven years in prison for walking through the open doors of the Capitol, taking photos in the hallway, and leaving without doing any harm.”
Louis Gohmert of Texas: (The DOJ is) “ criminalizing political protest — but only political protest by Republicans or conservatives.” “...there’s no evidence ... that this was an armed insurrection.”
But the few sane and honorable Republicans that remain in Congress know better. Like Liz Cheney and Peter Meijer who said:
“Unfortunately, many who rightly criticized and condemned the attack that day have walked back their words or softened their speech. But even more troubling, there has been an active effort to whitewash and rewrite the shameful events of that day to avoid accountability and turn away from difficult truths.”
