“.....both the WP and NYT reported last night that Trump does not plan to fire Mueller, but instead is setting his sights on Sessions and Rosenstein...”
I did read several reports quoting Trump as saying that he will not consider firing Mueller.
However, none of these quotes included anything like the second part of your paraphrase, namely, “....but instead is setting his sights on Sessions and Rosenstein...”
Do you have a link?
Yes, I put one in the thread just after the one you replied to.
