Trump has apparently posted a response to the committee’s referrals to DOJ. I say “apparently” because it is embedded in a video from something called Meidas Touch (a commentator I didn’t know about) and he says it was posted on Truth Social. I can’t confirm that. Here is the link, the Trump video starts at about 1:15. The printed comments around the video are from Meidas Touch.
I will say that he looks and sounds more deranged than ever. I didn’t watch the whole posted video, I just couldn’t stand it, but he does jump around from charge to charge and outright lies about pretty much everything. I assume this is targeted at “the base” but I don’t know what good that will do him.
