Here's an article from CNN talking about how Bannon is on thin ice. Everyone working for the President is on thin ice, obviously, so that's not what I'm interested in. What I'm interested in is this quote, c/o Anthony Scaramucci:
"I think the President knows what he's going to do with Steve Bannon. It's his decision. But I mean at the end of the day, I think the President has a very good idea of who the leakers are inside the White House. The President has a very good idea of the people that are undermining his agenda that are serving their own interests."
From what I've read the main whispers about who's doing the leaking have been about Kushner/Ivanka, and there were also some snide remarks made about the surprise(ish) firing of Reince Preibus (i.e. he was a leaker too). This is the first I've heard about Bannon leaking, and it's interesting that both Kushner and Preibus had serious disputes with him in the past, and that the President (who I think we can all agree has no hesitation tweeting his mind) has had no comment on these statements.
