Actually a zero. I have never watched such a bias, disrespectful, unfair and rude so called interview from someone I wouldn't even called a reporter. How she would ask a question and then no matter how the President would respond, she would argue with the President of the United States. This was obviously her plan from the very beginning. Right or wrong, I'm so proud that he walked out. No one should ever be disrespected as he was. She's a very vicious, and a very ugly, ugly person. There is absolutely no reason to attack and treat ANYONE with such disrespect. And listening to the candy coated questions to Biden and Harris, was clearly rehearsed, especially with those close-ups of Biden and every time he was asked a question. It's discussing and I'm discussed with 60 minutes to allow such a horrible, rude, bias and disrespectful interview on the air.
