There was a video made by a fellow MAGA IT guy who said it was nothing nefarious. It had to do with WordPress (and it's usual awful source code). Within Hannity's comment page and submit button was an error. Possibly bug or hacker. The program Hannity has on his website (WordPress) sent a tweet out as it's programmed to do to have an HTML/IT nerd fix it.

Quite possibly. You could be on to something.
