Presumption of innocence applies to court, not public opinion.
Read the indictment. They repeatedly told donors no one was getting paid a penny then they set up some behind the scenes schemes to funnel money into their personal accounts. Bannon got a million, Koflage got 350000 all the while swearing no one got a penny.
Since the govt traced the money from the donors to the defendants account I don’t see where they can deny it. Plus, they made a bunch of incriminating texts about keeping it secret!
You’d stab the President in the back if you thought an indictment of him by the Deep State looked ‘damning’.
