"I am doing what I want to do right now and I have no intention or any idea even of running again," Clinton told CNN last year.

"Hillary ClintonHillary Diane Rodham ClintonWhite House would like to see Biden ‘in the boxing ring’ in 2020 House Judiciary chair subpoenas DOJ for FBI documents The suit to make Electoral College more ‘fair’ could make it worse MORE, I think, is a terrific woman," Trump said. "I just like her. I like her and I like her husband."

Trump added that Clinton had done a "good job" in her current role as secretary of State.
