I checked a few of the linked sites. They all say an anonymous secret service agent revealed that the HBD (Huge Black Dude) is Todd Madison. Trunews and Fromthetrenches seemed to be the only ones saying it. Other than the WaPo article. None have an actual source.
So....no cigar.
FWIW- I know a few Doc's that carry concealed....but none wear a wire..Ha!!
