Donald Trump is CONTINUING his war with LaVar Ball -- this time ripping him as the "poor man's version of Don King, but without the hair."

Trump is clearly still pissed over LaVar's CNN interview -- in which Ball refused to thank POTUS for helping get his son LiAngelo Ball and 2 other UCLA teammates out of China after they shoplifted.
