Let's remind everyone just how the Trump cult traitors are lying here.
Barr, under the orders of Trump, ordered everyone to report to the FBI whatever fake story they could find or fabricate about the Bidens. Yes, Barr and Trump weaponized and politicized law enforcement like no one before or since.
Guiliani responded by sending some stories that supposedly came from a few unnamed sources. You know, entirely made-up stuff.
So yes, there's an "FBI report" about that.
The FBI examined that "evidence", and correctly concluded it was a big steaming pile.
The Republican House knows that. They want the report, but they'll only keep it to themselves, and not publicly release it. That's so they can cherrypick out the fake stuff Guiliani put in, while conveniently leaving out the parts where the FBI says it's all a big steaming pile.
As part of investigating the info, the FBI used info from their confidential sources, naming them in the process. They don't want Republicans leaking those sources and getting them tortured and killed. And we all know some Republicans would do that, with great joy. When has the Republican House ever _not_ leaked? And there's no treason the Trumpian death cult won't stoop to if it aids TheParty and MotherRussia. In Trump cult eyes, those confidential sources were inconvenient to TheParty, being how they told the truth, so they deserve to die.
Yes, the congressional Republicans really are that awful. And of course all of the Trump cultists here enthusiastically support the sleaze and dishonesty. That's who the Trump cultists are now, devoted minions of the Lord of Lies.
