For all his supposed experience, Mattis wasn’t too bright when he allowed Omarosa Manigault to record their conversation in the White House. Security breach, and he let it happen.
I think that was Allen.
Maybe Mattis allowed Omarosa to record private conversations because they are allied in the desire to remove this president, and always have been. Omarosa has been uncommonly quiet since her last book bombed. Even the media seems to have no more use for her, that, or she’s just a very difficult person to deal with in any manner.
