Parenting a child home from college and arguing with my husband

My daughter is home due to the pandemic and my husband and I are fighting about how he treats her. He can be very mean to her and then I stand up for her. I feel like a bad wife as I know we ideally should be on the same page, but I don’t know what to do when he makes her cry. He feels like I am taking her side and my daughter and I are ganging up on him. I really feel like he is being unfair to her. I love them both, and am not sure what the best step is for me when this happens. How can I help them both? What should I be doing when I feel like he is treating her unfairly?
