‘It’s OK’: Trump jokes Mamdani can call him a fascist (youtube.com)
It went something like this. The press presses Mamdani about calling Trump a fascist, and Trump taps Mamdani and says It's ok, you can just say it, and Mamdani smiles and it like yup, and Trump is like It's ok I've been called worse. It's just easier than explaining it to the press. Something like that.
