So, this headline happened: Mueller gives Trump’s legal team questions for potential interview:
Special counsel Robert Mueller has presented President Trump’s legal team with a list of questions as investigators seek an interview with the president.
The New York Times reported Saturday that the questions were a sort of starting point for Mueller, whose team is working to negotiate an interview with Trump as part of the investigation into Russia’s role in the 2016 election.
Up to the point, Trump had never used Mueller’s name in a tweet. That changed immediately:
So Trump is now laying the groundwork for his case for firing Mueller.
I’m putting this link here. It’s from Move-On and has a list of rapid response protests if (or more likely when) Trump acts on firing the special prosecutor.
