Not saying this is how it happened, but it's like this:
staffers:
A: Is there an official line saying we HAVE TO inform the president?
B: No
A: what happens if we don't?
B: Probably some bad press and some senators talking crazy
A: what if we tell them in advance?
B: That a$$hole at the White House, the chief of staff, will leak it to the press that Austin has been hospitalized for a possibly terminal illness, because he's been pushing to get rid of Austin, since they disagreed on some Iran policy decision.
