Let’s say the cabinet decided that this is finally it, he had crossed the rubicon, could they actually do it? Most of the cabinet hasn’t been approved by the Senate, which shouldn’t be possible. Almost all of them are acting, which should be allowed for a very short period of time but we have multiple people who have been “acting” for a year+.
The wording doesn’t allow for acting, and you know old Justice Roberts never met a hair he couldn’t split to help out the Republican cause, in the event it was challenged and brought to the Supreme Court.
