The 58-year-old television presenter didn't hold back as he questioned university professor Dr Simon Clarke in a discussion about Liverpool's lockdown.
Phil called out Clarke for saying the Liverpool lockdown is an "inconvenience".
Simon repeatedly told Phil he had never said that in the heated moment.
Phil probed: "You described the Liverpool lockdown as an inconvenience. Anyone watching in Liverpool now, bearing in mind we've certainly been concentrating on a great many people's mental health and their stability.
"The closing down of gyms, people don't just go for their physical health they go for their mental health as well.
"So you have Liverpool at stage three, the worst that we can get to, and so its just an inconvenience?"
Simon denied ever saying such a thing. He said: "No, I don't think I said that. I don't know where you've got that from, I just told you I think lockdowns are a failure..."
Phil interrupted and said: "I'll read you what you said. You said "In Liverpool the situation seems to have gotten out of control much quicker than anyone could reasonably have known and that they had to do something. It's bad if you work in the hospitality industry, but essentially it's just an inconvenience for everyone else" those are your exact words."
Simon replied: "That was before the lockdown was put out, so it was referring to the other restrictions that were put in place before that."
He added: "I have been quite clear and there are many, many interviews of me saying that I think lockdown..."
Schofield interrupted again and stated: "You made those comments last night in our research chat.
Simon shot back: "No I didn't!"
He continued: "I did not, I said that closing down the hospitality industry was an inconvenience, but so is filling the intensive care units with people who can't breathe."
