I know of no circumstance where Trump has made an unfounded accusation against Carson.
If you do, please share.
I am aware he has done nothing to dissuade the MSM in their frenzy...and has even played to their proclivities.
But I am aware of nothing, nothing that could be remotely described as character assassination.
This is an example of character assassination:

That’s all Trump has to say?
Nope, he brought the subject up — it’s his leading contender.
If Trump fails to help debunk any slanders and help broadcast any retractions, then he CERTAINLY IS being a character assassin.
That simple.
