There was an article about the J6 committee putting together their final report, and there were three or four groups that dealt with different aspects of the 'investigation'. Cheney headed the one group or was deeply involved, so much that there was a lot of internal distension within the other groups that Cheney was deviating from the 'investigation' and channeling the results into an campaign election effort for her. This report of her hiding exculpatory evidence isn't surprising at all. I forget who published the article, but the funny thing was, it was one of those heavy left leaning sites.
