How about this?
At the first debate on September 26 Trump said that Hillary Clinton lacked the stamina to be President.
Then on October 9, he said "She doesn’t quit, she doesn’t give up. I respect that. I tell it like it is. She’s a fighter. I disagree with much of what she’s fighting for. I do disagree with her judgement in many cases. But she does fight hard, and she doesn’t quit, and she doesn’t give up, and I consider that to be a very good trait.”
