This is not a point of dishonesty against Dr. Carson. That is only possible from others.
When asked about this Op-Ed, Dr Carson stated his staff is now working with Trump so it was not really plagiarism - Trump is pushing Dr Carson’s message is what is happening. The staffer that write that op-ed for Trump is probably the same person that wrote it for Dr. Carson. You did not thing Dr Carson or Trump does grunt work like write op-eds do you?
