Concern about China is not partisan anymore, pretty much everyone is on board now.
Also from the article:
"Officials said the agency was not bending its views to a new boss, and that the new assessment had been in the works for some time."
But we know Trump lies, and that people around him change their story and lie for him, and we know he gets rid of personnel who don't 'kiss the ring'... and this comes at the exact instant that he says he's going to start his import tariffs for Chinese goods and needs media support to convince USA-ians that making all goods coming from China now expensive is a good idea...
I mean you're going to need extraordinary evidence to show this is true; but CIA say there's no new evidence and it's a low confidence conclusion.
Probability that it's just Trump continuing to be deceitful and manipulative approaches certainty.
