I dont want to hurt the Clintons, I really dont, Mr. Trump said in an interview with the New York Times. She went through a lot and suffered greatly in many different ways. He also said the Clinton Foundation has done good work.

I think Trump may have made those statements knowing that at a later date, the Clintons will be prosecuted, and did not want it to appear that it is a personal vendetta against The Beast.
