Trump's various announcements yesterday (or is the  day before now)  on the day that the health bill imploded are all designed to get the message through, as subtly as Trump is able, that Trump will fire Mueller if he investigates Trump's finances.

News of the day in order
1.  Health bill imploding   
2.  Disgusting threats against Republican senators not supporting the health bill
3.  Comments about Sessions
4.  Comments about Comey
5.  If Mueller investigates Trump finances, that will be a red line

So, what are we all to assume?  That the real dirt that Trump is trying to hide is within his finances.
