Because there is no "thing".
Neither you, nor anyone else, has showed me one piece of information from these Twitter files at all.
What is wrong with you that you believe unsupported claims by people who refuse to document them?
And what exactly are these claims? You don't actually specify. No one does.
All I get is that "the Biden campaign asked us to remove some posts", which wouldn't be a smoking gun even if these posts weren't penis pictures.
I am embarrassed to read this thoroughly undocumented hit piece.
Please note that I'm not an American, do not live there, and am in no sense a fan of Biden or the Democrats at all: but I have a very low tolerance for BULLSHIT.
