Let's just begin with this: Steve Bannon does not care one whit about ethics rules and possibly even about the law. Steve Bannon lives a life where chaos and darkness are his friends, along with his white supremacist cabal of supporters.
Now let's see if we can educate POLITICO about that. In what can only be described as hopelessly optimistic, they have an article published about why Bannon can't have any contact with Breitbart while he serves in the White House.
It's almost as if they believe the usual ethics rules will apply to him!
President-elect Donald Trump’s chief strategist, Steve Bannon, would be prohibited from communicating with the alt-right website he used to run, Breitbart News, while serving in the White House, according to ethics rules currently in place.
Bannon’s appointment stoked fear among liberals and conservatives alike that he would utilize the fiery Breitbart.com — a site that regularly attacks House Speaker Paul Ryan and other Republicans, as well as liberal Democrats — as a semi-official house organ to promote Trump’s policies and attack his critics.
A couple of corrections to that first paragraph. First, it's not "alt-right." It's white supremacist fascism. Second, does anyone seriously think Trump or his pal Bannon give a fig about current White House ethics rules?
